It’s about 5.0~6.5 km on the strike and 2.5~3.5 km on the dip, with the 20 km2 total area. There are 2 minable coal seam. The main aquifer coal seam is 72 coal seam with an average thickness of 3 m, and the dip of 72 coal seam is 7~13°. The proved reserves of this coal mine are 327.898 Mt and the minable reserves are 249.35Mt, with a mine life of 197.9 a. The normal mine inflow is 525m3/h and the maximum mine inflow is 830 m3/h. The mine relative gas emission quantity is 12 m3/t, Thus, it is a high gas mine. The coal seam has spontaneous combustion tendency, and the coal dust has explosion hazard.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 level.and seam downward mining. the second is vertical shaft development with one mining level and rock downward mining. the third is vertical shaft development with two mining levels and dark inclined shaft extension. the last is vertical shaft development with two mining levels,and seam mining and dark incline shaft. The first project is the best comparing with other three projects in technology and economy. The first mining level is -600m, The mine field is divided into three strip districts and three mining district. 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 200 m, which uses fully mechanized mining with top coal caving 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 0.6 m, and the quantity of 2893.3 ton coal is maked everyday.Main roadway makes use of belt conveyor to transport coal resource, and mine car to be assistant transport. The main shaft uses two double 6 t skips to lift coal and the auxiliary shaft uses a twins wide 1.5 t four-car double-deck cage to lift material and personnel transportation.The monographic study entitled “Principles of Technical Analysis of coal mine water prevention and control”. The study is contain underground water sources and underground water channels, as well as prevention of water -related theory and the corresponding measures.The translated academic paper is about Grey Theory of Coal mine water forecasting.the article entitled Grey forewarning and prediction for mine water inflowing catastrophe periods.Keywords: shaft; one mining levels; strip district; fully mechanized mining with coal caving; centralized juxtapose ventilation目 录1 矿区概述及井田地质特征
