Gaysky GOK is building an underground pipeline more than a kilometer long
Guy (Orenburg region)
The staff of the Mine Construction Department of PJSC "Gaysky GOK" (an enterprise of the raw materials complex of UMMC) is building the first stage of the underground crushing and conveyor complex "Porodny tract - 2". The complex is located in the interval of 1230-1340 meters and is intended for the delivery of rock mass from the lower horizons along the shaft of the Skipovaya mine. Let us explain - in the process of conducting mining operations, a large volume of rock mass is formed, which is delivered to the loading point into the skips of the Skipovaya mine by self-propelled equipment - loading and haul-off machines, dump trucks. The commissioning of the crushing and conveyor complex will allow to reduce the length of haulage of the rock mass by self-propelled equipment, which will affect the reduction of costs and increase the efficiency of the use of self-propelled equipment.
“Construction of this crushing and conveyor complex will ensure the delivery of rock mass from the ore field to the shaft of the Skipovaya mine with its subsequent delivery to the "mountain". First of all, the complex is necessary for the mine builders themselves for the stable operation of the workshop. According to the plan, the new facility will provide for the output of rock in the amount of up to 1370 thousand tons per year, - said the chief engineer of the Gaysky GOK Nikolay Efimov.
"Porodny trakt-2" includes two conveyor galleries - No. 17 and No. 17A with a total length of 1010 m, 2 chambers with crushing plants, a rolling conveyor chamber, three chambers of local underground feeding substations, an overload chamber with drives of conveyor gallery No. 17a, a sump pumping station, a complex of rock runs from 1150 m horizon to 1340 m horizon and other auxiliary facilities.
At the first stage of the construction of this complex, the mine builders performed a very large and technologically complex scope of work: the excavation of capital mine workings with a total length of more than one kilometer was completed. “On conveyor gallery No. 17, installation preparatory work for the installation of the conveyor has been completed by 80 percent, on gallery 17A - about forty percent. In general, the total weight of the assembled metal structures is expected to be about 300 tons, excluding the weight of the equipment, - said the head of the ShSU Nikolay Zatsepin.
Currently, in parallel with the assembly work on the conveyor galleries, a crushing plant chamber is being built. The construction and equipping of one section underground substation for feeding the conveyor gallery No. 17A is nearing completion.
Let us remind you that Gaysky GOK is carrying out a large-scale reconstruction of the Underground mine in order to maintain and increase the volume of ore extraction. The reconstruction is carried out within the framework of the project "Opening and development of deep horizons at the 830-1310 meter level of the underground mine of the Gaysky GOK", provided for by the strategic program for the development of the mineral resource base of the UMMC.
