Sima coal mine is located in Changzhi, Shanxi province. It’s about 4.17~5.90km on the strike and 3.10~5.95 km on the dip, with the 24.949 km2 total horizontal area. The minable coal seam is 3# with an average thickness of 6.62 m and an average dip of 3.8°. The proved reserves of this coal mine are 249.64 Mt and the minable reserves are 234.45 Mt, with a mine life of 69.8 a. The normal mine inflow is 220 m3/h and the maximum mine inflow is 300 m3/h. The mine gas emission rate is 0.67 m3/t which can be recognized as low gas mine. Based on the geological condition of the mine, this design uses a duel-vertical shaft single-level development method, and full strip preparation ,which divided into eight bands and two districts, and track roadway, belt conveyor roadway and return airway are all rock roadways, arranged in the floor rock of 3# coal seam. Taking into account of the high gas emission, mine ventilation method use two diagonal wings ventilation, and excaves bottom gas drainage roadway before mining to relief gas pressure in advance.The design applies strip preparation against the first band of East One which divided into 4 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing.The design conducted coal mining technology design against the 3101 face. The coal seam average thickness of this working face is 6.62 m and the average dip is 3.8°, the immediate roof is mud stone and the main roof is sand stone. The working face applies fully mechanized longwall full-height coal caving method, and uses double drum shearer cutting coal which cuts twice each working cycle. “Three-Eight“ 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 battery locomotive to be assistant transport. The main shaft uses double 12 t skips to lift coal with a balance hammer and the auxiliary shaft uses a twins narrow1.5 t four-car double-deck cage and a wide 1.5t four-car double-deck cage to lift material and personnel transportation.The monographic study entitled “Case Study and Research of Deep Soft Rock Pressure Observation“, the study took bottom gas drainage Roadway of Sima Mine 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 “ Numerical Simulation of Coal Floor Fault Activation Influenced by Mining “.Keywords: double vertical shaft; band mode; full-height coal caving; two diagonal wings ventilation; soft rock roadway; pressure observation目 录摘 要
