4、RACTThis design includes three parts: the general part, the special subject part and the translation part.The general part is a new design for Gengcun mine. Gengcun mine is located in Yima western Sanmenxia mining area in Mianchi County, North3.2km from Mianchi County, northeast 15km from Yima, west

5、 53km of Sanmenxia City, East 69km from Luoyang City, convenient transportation.The maximum length of the coalfield is 5.39km,and the minimum length of the coalfield is 4.87 km , The maximum width of the coalfield is 3.65 km,and the minimum length of the coalfield is 2.52 km,and the total area is 15

6、.21 km2.The third are the main coal seams, and its dip angle is 812degree. The thickness of the mine is about 8.69m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 177.93 million tons,and the minable reserves are 119.09 million tons. The desig

7、ned productive capacity is 1.5 million tons percent year, and the service life of the mine is 56.71 years. The normal flow of the mine is 45m3 per hour and the max flow of the mine is 176.8 m3 per hour. The relative mine gas gush is 4.94 m3/t and the absolute gush is 4.27 m3/min, so it is a low gas

8、mine. The mine is a double levels to develop. The central laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway . The prophase ventilation mode of this mine is center juxtapose form, and the late ventilation mode of this mine is diagona

9、l form. The “three-eight” working system is used in the Tunliu mine. It produces for 330 days a year.The deneral 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 coal

10、field; 5.The layout of panels; 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 part is cross m

11、ining drift wallrock deformation regularity and supporting technical analysis, the paper analyzes the across adopt drift wallrock deformation and the factors affecting the deformation regularity, and from across the roadway deformation caused by mining, analyses the factors in recent years in the cr

12、oss of roadway supporting theory and technology, from engineering example analyzed the grunting reinforcement to cross mining roadway effect.Translation part is about relationships between gas reservoir and the evolution of stope Surrounding rock fracture at the process of mining the Closed distance

13、 protection layer.The English title is “Relationships between gas reservoir and the evolution of stope Surrounding rock fracture at the process of mining the Closed distance protection layer”.Keywords: Shaft; Double level; Panel; Center juxtapose ventilation; diagonal form; full-seam mining目 录一般部分1
