The mine service life isT=ZAK=70 yearsIt meets the requirements of "Code for Design of Coal Industry Mines".3.2.2 Well Type CheckAccording to the actual coal seam mining capacity, auxiliary production capacity, storage conditions and safety conditions of the mine, the well type shall be calibrated:1, coal seam mining capacityThe 8th coal seam of the main coal seam in the mine field is a thick coal seam with stable occurrence and little change in thickness. According to the development mode of "one mine, one well, one side" in modern mines, a large mining height working face can be arranged to ensure production.2, auxiliary production capacity checkThe mine is designed as a large-scale mine, and the development method is to go up and down the mountain at a single level for double vertical shafts. The main shaft adopts skip to lift coal, while the auxiliary shaft adopts cage to lift coal. The coal lifting capacity and lowering of large equipment can meet the requirements of design shaft type. The raw coal produced in the working face is transported to the coal bunker at the bottom of the shaft by the belt conveyor along the trough to the main lane and then lifted to the ground by the skip in the main shaft, thus realizing continuous transportation of the main lane with large transportation capacity, simple operation and high automation degree. Auxiliary shaft adopts cage to lift and lower materials, which can meet the lowering and lifting of large equipment. The auxiliary transportation in the main roadway adopts electric locomotive to pull tramcar for transportation, with large transportation capacity and convenient and flexible dispatching. Therefore, the auxiliary production link can fully meet the requirements of design production capacity.3, check the ventilation safety conditionsMine gas emission is large, which is a high-gas mine. Coal dust has explosion risk. The main development alleys in the mine adopt two alleys for air intake and one for air return, and there is a special air shaft for air return, which can meet the needs of ventilation.4, production capacity and service lifeThe design and production capacity of the mine should be adapted to the industrial reserve of the whole mine to ensure sufficient service life to meet the requirements of the "Code for Design of Coal Industry Mines
