依据绿水洞矿井地质构造和煤层构造变形特征,对该矿煤层(成)气赋存运移规律进行了系统的分析,就该矿生产中煤层(成)气涌出及可能产生的动力现象进行了地质评价,认为在矿井深部仍存在沿岩层裂隙和溶洞发生煤层(成)气涌出的可能,田湾向斜东翼为全井田煤层(成)气突出危险程度最高的区域。
According to the geological structure of the mine and geological characteristics of the coal seam, the occurrence and migration of coal seam (gas) in this coal mine are systematically analyzed. As a result, The geological evaluation shows that there is still the possibility of coal (gas) gushing out along the rock fissures and karst caves in the deep mine. The eastern wing of the Tianwan syncline is the area with the highest risk of coal seam (gas) formation in the whole coal field.
