Gobei mine is located in Bozhou City, Anhui province. the traffic is convenient.The length of the coalfield is 6km,the width is about 3.2km,and the total area is18km2.The 8th is the main coal seams with average dip of 18°.The thickness of the mine is about 8.5m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 168.46 million tons and the minable reserves are 102.33 million tons. The designed productive capacity is 1.5 million tons percent year, and the service life of the mine is 52.5 years. The normal flow of the mine is 250m3 per hour and the max flow of the mine is 280m3 per hour. The relative mine gas gush is 6.77 m3/t and the absolute gush is 21.3m3/min, so it is a low gas mine. The mine is a vertical shaft development with two mining levels and the extension of blind inclined shaft. Te central laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway.The ventilation mode of this mine is center juxtapose form.The design applies district preparation against the first district of East One which divided into five longwall faces totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing.The design conducted coal mining technology design against the 8101 face. The coal seam average thickness of this longwall face is 8.5 m and the average dip is 24°, The face applies fully-mechanized coal caving mining 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 0.6 m with two working cycles per day, and the advance of a working cycle is 2.4 m. So the advance is 72m per month.This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.development engineering of coalfield; 5. mining district preparation; 6. The method used in coal mining; 7. Underground transportation of the mine; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms of the designed mine.The topic of special subject parts is Analysis of Coal Mine Gas Disaster and Prevention Technology. It mainly introduces the gas disaster and regularity, coal and gas outburst prevention and control and gas drainage technology.Translation part is a study on control fire in undergound coal mines numerical moddlling of pillar strength.The English title is: Recent Developments and Practices to Control Fire in Undergound Coal Mines.Keywords: Vertical shaft; Blind inclined shaft; Two level; mining district preparation; Center juxtapose ventilation; Coal caving mining目 录一般设计部分1 矿区概述及井田地质特征
