It contains ten chapters: 1.overview and the geographical features of the mining field; 2.boundary and reserves of the mining field; 3.working system, designed mine capacity and mine life; 4.development of mining field; 5.preparation in Roadway layout; 6. mining method; 7.underground conveying; 8.mine exaltation; 9.mine ventilation and safety; 10. the basic technical and economic index of mine.Yaoqiao mine is located in Pei County, Jiangsu Province, and Weishan County, Shandong Province, and it lies in the west of Zhaoyang Lake. The traffic is very convenient. Mine field east-west direction length is 10.69km average and north-south tilt of the average length of 4.11km. The mine field coal district level area 39.74km2. The minable coal seam of this mine is only 7 with an average thickness of 6.63m and an average dip of 8.83°, field 371.21Mt for industrial reserves, recoverable reserves 264.65Mt, the mine for a service life 63.01a. Coal grades for the quality of gas coal. The mine is the low gas mine, the gas absolutely emission 0.0384m3/min. This mine coal seam spontaneous combustion has a natural ignition propensity to spontaneous combustion period is less than three months. Normal inflow of the mine is 508m3/h, the largest inflow of the mine is 607m3/h.Mine a double vertical shaft single level development, pre-central breakdown of ventilation, the late mine field east and west wings of the establishment of a boundary air shaft to form a diagonal ventilation. As the mine geological conditions, and tilt the seam for ease, in order to facilitate with the mining with the grouting, so the entire layout of the mine mining area, the system is simple, reliable, easy to manage. Design of mine is a well side of the production, mining method for fully mechanized coal caving mining method. Coal transportation by belt conveyor transport, auxiliary transport cog rail vehicles in the explosion-proof diesel traction fixed van tramcar transport.We work 330 days per year ,and exaltate 16 hours one day .The “four–six” working system is applied for coal mining .The thematic part of the topic of the coal seam gas drainage technology.The translation part is about the analysis and control on anomaly water inrush in roof of fully-mechanized mining field, the original English text entitled: Analysis and control on anomaly water inrush in roof of fully-mechanized mining fieldKeywords:New
