The general design is about a 1.50 Mt/a new underground mine design of zhang xiao lou coal mine. Zhang xiao lou coal mine is located in xuzhou, Jiangsu province. It’s about 4.8 km on the strike and 3.53km on the dip, with the 16.54 km2 total horizontal area. The minable coal seam is 7# and 9# with an average thickness of 6.0 m and 3m .The Two layers of coal are 10 m apart.They are very close. The Two layers of coal has a larger change dip , shallow average of 20° , deep average of 5°. The normal mine inflow is 76 m3/h and the maximum mine inflow is 160 m3/h. The mine gas emission rate is 3.35 m3/t which can be recognized as low gaseous mine. The proved reserves of this coal mine are 205.39 Mt and the minable reserves are 137 Mt, with a mine life of 65.24 a. Based on the geological condition of the mine, this design uses a duel-vertical shaft two-level development method, and full strip preparation ,which divided into seven districts and two strips, The first level is located -600 m ,and rise horizon interval is 320 m , and dip horizon interval is 250 The second level is located -1150 m ,and rise horizon interval is 300 m , and dip horizon interval is 100 m. Track roadway, belt conveyor roadway are all rock roadways, arranged in the floor rock of 9# coal seam. Taking into account of the low gaseous emission, mine ventilation method use centralized parallel ventilation. Main roadway makes use of belt conveyor to transport coal resource, and battery locomotive to be assistant transport. The main shaft uses skips to lift coal with a balance hammer and the auxiliary shaft uses cage to lift material and personnel transportation. The design applies strip preparation against the first districts of East One which divided into 3 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing. The design conducted coal mining technology design against the 7101 face. The coal seam average thickness of this working face is 6.0 m and the average dip is 20°, the immediate roof is mud stone and the main roof is sand stone. The working face applies fully mechanized longwall mining with sublevel caving 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 0.6 m with six working cycles per day, and the advance of a working cycle is 3.6 m and the advance is 108 m per month. The monographic study entitled " The relation between rockburst and the law of Microseismic in zhangxiaolou coal mine", the study took 95206 workface as an example, conducted a detailed pressure observation data collection and processing, gave the deformation and convergence law of soft rock roadway, which had significant guidance for practical mine production. The title of the translated academic paper is " Mine gas drainage and outburst control in Australian underground coal mines ",Used in Australia.
