5、of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.The Xiegou mine locates at the crosspart of Xingxian, Lvliang in Shanxi province, 50 km away from the center of the town. And the transportation is very convenience. The total plane area o
6、f the mine is about 21 km2. There are two coal seams in the mine NO.8 and NO. 13. Mining the NO.8 coal seam firstly.The angle is about 812 degree with an average of 9 and the thickness of both coal seams is about 6.0 m. The minefield geological condition is simple.The proved reserves of the minefiel
7、d are 566.13 million tons. The recoverable reserves are 455.37 million tons. The designed productive capacity is 5.0 million tons per year. The service life is 60.12 years. The normal water flow of the mine is 77 m3 per hour and the max water flow is 133 m3 per hour. The Relative gas discharge quant
8、ity is 10 m3 per ton, whichmeans it is a low gaseous mine. The coal seam is hardly spontaneous combustion and the level of spontaneous combustion is . Apart from coal without gas, the coal seam is of high explosion hazard.The development of the mine is double levels with vertical shaft at the first
9、level. The number of the working faces is only one. The mining method is Comprehensive mechanization with putting off the top coal technology. Several belt conveyers undertake the job of coal transport in the mine and the auxiliary transportation system is centralized juxtapose. The ventilation meth
10、od is diagonal ventilation system.We work 330 days per year and exaltate 16 hours one day. The “threeeight” working system is applied for coal mining.The title of the special subject part is “Coal and gas outburst prevention and control technology”. The translation prat is a paper about gas extracti
11、on technology of single coal seam with low permeability.Its title is “Effect of grout properties on the pull-out load capacity of fully grouted rock bolt”.Keywords：design of mine; top-coal caving; diagonal ventilation system 目 录一般部分1矿区概况及井田地质特征11.1矿区概述11.1.1井田位置及交通11.1.2地形与地貌11.1.3气候条件11.1.4水文情况21.1
