| 摘 要： | 宣城市金宝煤矿是皖南小型煤矿,地质条件复杂,开采难度较大,若采用传统的支扩方式开采,巷道维修工程量大,留设的保护煤柱量大.为了改变此现象,根据矿压理论及矿压显现规律的调查成果,对巷道支护形式,巷道布置,采煤方法进行改进,取得了一定的效果.

| Abstract: | Jinbao coalmine is a small one in Xuancheng City, south Anhui, with complicated geological conditions and bigger difficulty in mining. If traditional method of supporting and extension is adopted, the tunnel maintenance work is huge and the reserved protective coal pillars are tremendous as well. To change this, in recent years, we made improvements in the way tunnels were supported, the lay-out of tunnels and the mining method, based on mine pressure theory and the survey results of the regularity of show of mine pressure, with positive results shown in this paper. |
