The method used in coal mining; 7. Transportation of the underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.The general part is a new design of Pingdingshan mine with a production of 1.2 million t/a. Pingdingshan mine lines in Pingdengshan city, HeNan province. The traffic of road and railway is very convenience to the mine. The run of the minefield is 4.83 km ,the width is about 5.84 km, well farmland total area is 25.44 km2. No. 4 are the main coal seam, and its dip angle is 2~17°, 7° for average. The thickness of the mine are about 3.45 m. The geological conditions of the minefield is relatively simple.The proved reserve of the minefield is 187.7 Mt. The designed productive capacity is136Mt, and the service life of the mine is 81years. The normal water flow of the mine is 548 m3/h and the max flow of the mine is 1070 m3/h. The relative gas emission rate of the mineral well is 5.94 m3/t, for low gas mineral well.Based on the geological conditions of the mine, I bring forward four available project in technology. The first is vertical shaft development with one mining levels, the deep extension of blind slope; the second is vertical shaft development with two mining levels; the third is vertical shaft development with one mining levels and the deep extension of blind slope,and the last is slope shaft development with two mining levels. The four project is the best comparing with other three projects in technology and economy. The first mining level is -300m, the second mining level is -580m. The mine field is divided into seven strip districts and one mining district. Taking into account the long distance in the east and west direction, The type of mine ventilation is the centralized juxtapose ventilation.Designed first mining district makes use of the method of the mining district preparation. The design length of working face is 210 m, which uses fully mechanized mining with full-seam mining technology. The working days in one year are 330. Everyday it takes 16 hours in lifting the coal. The operation mode in the mine is “three-eight” with two teams mining and the other overhauling. Every mining team makes three working cycle. So everyday there are 6 working cycles. The advance of a working cycle is 0.656 m, and the quantity of 3920 ton coal is made everyday.Special subject part of topics is: The impact of coal seam gas pressure control and applicationThe translated academic paper is the shearer mining application to soft thin-seam with hard roofKeywords:two levels of slope mining ; strip district; centralized juxtapose ventilation; full-seam mining 目
