Continuous Improvement with New Pumps at Volcan Compañía Minera

 

Written by Miguel Jahncke, October 6, 2015 (ver la versión española de abajo)

At an auction in 1997, Volcan Compañía Minera S.A. acquired Empresa Minera Mahr Tunel SA, which owned the San Cristobal and Andaychagua mines. After several other acquisitions and expansions, Volcan Compania Minera SAA has become one of the top ten producers of zinc, silver, and lead in the world.

Ticlio is high in the Peruvian Andes at over 4,800 meters above sea level. The history of the mining operations in Ticlio, which are now part of the Volcan operating units, dates back to 1943 when the first mining operations began in this area. After more than half a century, these mines continue to contribute to the economic growth for not only the area but for Volcan as well.

Andaychagua Mines

Working at these elevations is not easy. It’s made even more difficult because of the necessary extracting procedures at Andaychagua, where they are utilizing descending cut and fill mining methods. This mining method requires the use of cemented tailings filled with crushed waste rock and large amounts of steel rebar, creating strong roof support slabs to protect the miners and the mining process below.

Andaychagua has relied on this mining method for many years using Schwing pumps, which have provided reliable service for over 10 years. To keep operations running smoothly, Schwing Bioset recently supplied a new pair of KSP 65 HPR industrial pumping units with 400 HP power units to replace the trailer mounted pumps. These new industrial grade pumps will allow Andaychagua to extend the replacement interval of the pumps in the backfill operation. The first unit was commissioned last July and the second will be installed this month (October 2015). Each of these units has been set-up for dual purpose flow ranges of 46 m3/hr @ 147 bar or 70 m3/hr @ 94 bar.

Volcan – Unidad Andaychagua – Desafiando y venciendo retos para mejora continua

Escrito por Miguel Jahncke, 6 de Octobre, 2015

La historia de las operaciones de Volcan en las Alturas del abra de Ticlio, localizado en los Andes Peruanos sobre los 4,800 msnm, se remonta al año 1943, cuando se iniciaron las primeras labores mineras en esta área. Después de más de medio siglo estas minas no solamente siguen aportando a la minería sino que continúan con su crecimiento operativo, es.

En 1997 Volcan Compañía Minera S.A. adquirió en subasta pública la Empresa Minera Mahr Túnel S.A., propietaria de las minas San Cristóbal y Andaychagua. Luego de varias otras adquisiciones y expansiones, Volcan Compañía Minera S.A.A. se ha convertido en una de las diez principales empresas productoras de zinc, plata y plomo del mundo.  

Trabajar a estas elevaciones no es fácil y más todavía cuando hay que hacerlo con el sistema de corte y relleno descendiente como se opera en la unidad Andaychagua. Este método de minado requiere del uso de relleno con relave cementado y roca fina, además de estructuras con barras de acero  para poder darle a las losas superiores la estabilidad y resistencia necesaria para soportar los trabajos de minado inferiores. Andaychagua ha dependido de este método por muchos años utilizando para el relleno unidades de bombeo Schwing. Recientemente llegaron a Andaychagua reemplazos para  las unidades de bombeo montadas sobre tráiler que operan en la unidad. Estos dos equipos de bombeo nuevos son Schwing Bioset modelo KSP65 HPR con unidades de potencia de 400 HP. La primera unidad fue comisionada en Julio pasado y la segunda será instalada durante el mes de Septiembre. Cada una de estas unidades es capaz de bombear rangos de flujos de hasta 46 m3/hr @ 147 bar o 70 m3/hr @ 94 bar.

Miguel Jahncke, Director Global de Minería de Schwing Bioset estuvo presente durante el arranque de la primera unidad KSP65 HPR en Andaychagua en Julio, 2015.

New Pair of Piston Pumps for Big Island Mine

 

Written by Dale Bone, August 12, 2015

 

OCI Chemical Corporation is an industry leader in the production of soda ash, sodium percarbonate, and hydrogen peroxide. OCI’s Big Island Mine has been in operation since 1962 and is a 3.25 million short ton facility. The trona mine uses the “Room and Pillar Method,” and then they convey it to surface where it is refined into dense soda ash. The waste material is pumped back underground as far as two miles.  The tailings range from 50-63% solids. Soda ash is commonly used in glass manufacturing and powder detergent. Other uses include pulp processing, chemicals manufacturing, pH control, and food manufacturing.

OCI needed to replace aging piston pumps at its Big Island Mine near Green River, WY, and they chose to install Schwing Bioset equipment to pump their tailings underground or to surface storage facilities - on a 24/7 basis.  Because of this continuous demand, OCI spent a great deal of time and research in choosing a product and partner, and during this process they visited Schwing Bioset operations, among others. In the end, several factors drove the decision to choose Schwing Bioset piston pumps, and OCI will install two model KSP 220 pumps with XL poppet valves this fall.

According to OCI Project Manager, Mr. Jim Spurrier, the most compelling factors included Schwing Bioset’s resume of satisfied mining clients, their ability to customize programming and electrical design to integrate into OCI’s existing controls and computers, and the open loop hydraulics and hydraulic signaling incorporated in the product design.  The other important factor was that Schwing Bioset is based out of Wisconsin. The pumps and power units were built in Somerset, WI, so schematics were written in English, and the ability to get parts stocked in North America and shipped within one business day was critical, as well as having service techs in the US.

The information exchange and interaction the OCI team had with the Schwing Bioset team throughout the year-long process gave OCI the confidence that they chose the right partner for them and that they could make the project a success regardless of the challenges they face along the way.

Keeping the deeps dry

Carly Lovejoy explores the types and configurations of dewatering pumps used in underground mines, as well as current industry trends

Every underground mine has to deal with some degree of water ingress, and will require dewatering at one time or another during its lifecycle. How that dewatering is achieved, and the scale of the operations is largely dependent upon the mining method and design used, the depth of the mine, its location, the geology of the host rock and the type of ore being mined.

The geology of the host rock is a critical factor affecting the amount of water that needs to be removed. The porosity of the rock will determine the ability of groundwater and throughflow from natural sources such as precipitation to travel through certain layers of strata. Fractures, voids and veins can also act as conduits for water as it filters through the rock. Due to gravity, water will naturally follow through these channels, run down cave and tunnel walls and accumulate in depressions, whether natural or made-made.

Gavin Doran, general manager of sales at Sulzer Pumps (South Africa), says: “Open-pit mining sees the ingress of direct rainfall water, as well as overland or storm water flows into the operation, while underground mines see water ingress via rainfall down shafts and adits, as well as seepage of rainfall and overland flow from crack zones in geological structures, and water from pressurised aquifers that have been around for thousands of years.”

Mining in the proximity of large surface bodies of water or near coastal areas is also a concern and can lead to much greater degrees of flooding.

In addition to natural sources, water is also used at many stages in the mining process, for example, to flush cuttings from drill holes during development or production activities, and to suppress dust. This can add to the problem of naturally occurring water.

Miguel Jahncke, director of mining at Schwing Bioset, says: “Hard-rock underground mines generally have to deal with two main water sources: water that is present in the surrounding ground and enters the operation through troughs, voids, cavities, and drill holes; and water that is introduced through the mining process, through drilling, and face and muck pile hosing to suppress dust (silicosis prevention is the number one reason for keeping dust down underground).

“To prevent mining into unknown underground water bodies and ‘rivers’, development longholes are typically drilled ahead of the development headings and new mining areas to identify and eliminate, where possible, potential risks. All of the water in the mine is then collected and channelled to the lowest point through a series of channels or ditches.”

As water travels through the mine, it collects the fine particles of the rock (sometimes called fines or slimes) generated by the mining process. Downward dipping sections and working areas will collect additional water that can be pumped utilising small electric or pneumatic diaphragm pumps, or small submersible pumps. This water is pumped either to the mine dewatering channels or to one of the mine sumps. As the water reaches the lowest point of a mine, a series of settling ponds are typically used to settle the slimes, and supply cleaner water to the main sump where the main dewatering pumps are situated. These pump the water up to intermediate stages or directly up to the surface.
