Zhangshuanglou coal mine is located in Xuzhou, JiangSu province. It’s about 9.52 km on the strike and 3.27 km on the dip, with the 32.06 km2 total horizontal area. The minable coal seam is 9# with an average thickness of 5.8 m and an average dip of 20°. The proved reserves of this coal mine are 267.74 Mt and the minable reserves are 173.19 Mt, with a mine life of 74 a. The normal mine inflow is 294 m3/h and the maximum mine inflow is 453 m3/h. The mine gas emission rate is 1.64 m3/t which can be recognized as low gas mine. Based on the geological condition of the mine, this design uses a shaft two level(dark deep inclined shaft extension) development method, and full mining area preparation ,which divided into ten mining area, and track roadway and belt conveyor roadway are all rock roadways, arranged in the floor rock of 9# coal seam. Taking into account of the low gas emission, mine main ventilation method use central listed ventilation. The design applies mining area preparation against the first band of West Two which divided into 11 section totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing. The design conducted coal mining technology design against the 9201 face. The coal seam average thickness of this working face is 5.6 m and the average dip is 19°, the immediate roof is sandy mudstone and the main roof is mudstone. The working face applies longwall top coal caving mining mining method, and uses double drum shearer cutting coal which cuts twice each working cycle. "Four-Six" working system has been used in this design and the depth-web is 0.8 m with six working cycles per day, and the advance of a working cycle is 4.8 m and the advance is 144 m per month. Main roadway makes use of belt conveyor to transport coal resource, and DC overhead line electric locomotive traction fixed box-type tramcar to be assistant transport. The main shaft uses double 12t skips to lift coal with a balance hammer and the auxiliary shaft uses multirope friction hoist mention and a standard cage. The monographic study entitled " Longwall Face Gas Emission Law and Gas Emission Prediction ". This article discusses the basic law of the mode of occurrence of the coal seam gas adsorption of coal gas and coal seam gas migration and by data collection, collation and analysis, summed up the gas concentration distribution of mechanized mining face and goaf gas flow and concentration distribution of the law. The title of the translated academic paper is " Efficient mine microseismic monitoring ". This paper mainly introduces the important issue of efficient mine microseismic monitoring programs.
