摘要
通过对超化煤矿瓦斯地质状况分析,得出矿井煤层在构造作用下形成构造煤的特征,煤的坚固性系数在0.1～0.3之间;煤层瓦斯压力随采深及在构造影响下,呈现不规则增加趋势,最小0.35 MPa,最大2.6 MPa,对获取瓦斯赋存的相关特性及规律带来了极大难度;矿井发生3次动力现象均与断层有关,表明了地质构造是该矿煤与瓦斯突出的必要条件。
By analyzing gas geological conditions of Chaohua Mine, the paper obtained the characteristics of tectonic coal under the action of the geological structure, such as, the consistency coefficient of coal is 0.1 - 0.3, the gas pressure of coal seam appeared increasing trend irregularly due to the increase of mining depth and influence of the geological structure. Three times dynamic phenomenon in Chaohua Mine was related to fault, it shows that the geological structure is the necessary conditions of gas outburst in the mine.
