Transportation of the underground; 8.The lifting of the mine; 9. The ventilation a
5、nd the safety operation of the mine; 10.The basic economic and technical norms.Xiaoyugou mine locates at the northeast of zhungeer Mine area, it has a length of 3.8 km in the east and west direction while a width of 3.0 km in the south and north direction on average. The total area is Approximately
6、11.4 km2. The main coal seam in the mine is only one, which is the 6# coal seam. The average angle is 3 degree, while the thickness is about 12.0 m. The minefield geological condition is simple.The proved reserves of the minefield are 92.33 million tons. The recoverable reserves are 87.61 million to
7、ns. The designed productive capacity is 1.2 million tons per year. The service life is 56.16 years. The normal flow of the mine is 20 m3 per hour and the max flow of the mine is 30 m3 per hour. The Relative gas discharge quantity is 1.08 m3 per ton. Thus it is Low gaseous mine. The coal dust of the
8、mine has non-explosion hazard. But the coal seam is easily spontaneous combustion. The level of spontaneous combustion is I.The development of the mine is single level with slope development. The number of the working faces is only one. Comprehensive mechanization puts in the top coal technology is
9、the mining method. Several belt conveyers undertake the job of coal transport in the mine, while the auxiliary transportation system depends on the trackless rubber-tyred car. The ventilation type is centralized juxtapose.The working days in a year are 330. Everyday it takes 16 hours in lifting the
10、coal. The working system in the mine is “three-eight”.The title of the special subject part is “The theoretical research on the prediction of grout amount in backfill of collapse zone in coal mining”. A prediction method of grout amount in collapse zone is put forward by studying the regularity of t
11、he virgin roof movement and rock crack-expansion in the collapse zone, which provides a basis for the backfill project in collapse zone.The translated academic paper is about the rock bolts. Its title is “Analytical models for rock bolts”.Keywords: strip district; comprehensive mechanization puts in
