Chensilou coal mine is located in YongCheng, HeNan province. It’s about 6.5 km on the strike and 3.79 km on the dip, with the 24.69 km2 total horizontal area. The minable coal seam is Two-2 with an average thickness of 3.54 m ,the average dip is 9.73°. The proved reserves of this coal mine are 126.88 Mt and the minable reserves are 87.11 Mt, with a mine life of 55.8 a. The normal mine inflow is 894 m3/h and the maximum mine inflow is 1200 m3/h. The mine gas emission rate is 1.0 m3/t which can be recognized as low gas ,water inrush mine. Based on the geological condition of the mine, this design uses vertical shaft double-level development method, both district and strip preparation ,which divided into 3 strips and 5 distrits totally, The first level is at -540 m, The second level is at -900 m .Track roadway, conveyor roadway and return airway are all rock roadways, arranged in the floor rock of Two-2 coal seam. The design apply strip preparation against the first band of One which divided into 10 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing. The first stirp’s life is 16 months.The design conducted coal mining technology design against the 2106 working face. The coal seam average thickness of this working face is 3.54 m and the average dip is 8°, the immediate roof is day sandstone and the main roof is sand stone. The working face apply fully-mechanized long-wall full-height coal caving method, and using double drum shearer cutting coal which cutting twice each working cycle. “Three-Eight” working system has been used in this design and the depth-web is 0.8 m with five working cycles per day, and the advance of working cycles is 4.0 m per day and 120 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 wide 1.0t four-car double-deck cage to lift material and personnel transportation.The monographic study entitled “ Discussion of the drainage of the gas “ .This paper summarizes and reviews the achievements and lasted advances of methane harness and drainage theory and its applying. It is pointed out that the distribution configuration of mining fissured in overlying stratum and the methane delivery law in mining fissured are the research emphasis in the future, and are the theoretical base of fulfilling the safely simultaneous extraction coal and coalbed methane.The title of the translated academic paper is “ Method of branch ariflow fcalculating a complicated mine ventilation networks “. the method takes the branch airflow and fan working points as basic input data, and the present solution is of greater advantage for calculating ventilation networks of mines in operation.Keywords:Chensiloucoal mine; vertical shaft double-level; band mode; large mining height; 中国矿业大学 2012 届本科生毕业设计water inrush; gas draina目 录一般部分1 矿区概述及井田地质特征
