瓦斯喷出是煤矿在深部采掘过程中发生于地质体里的一种动力现象,在引起瓦斯喷出倾向的影响因素中,地质条件起着决定性的作用。另一方面,由于采掘生产活动,即对岩体力平衡状态的干涉破坏,导致了由地质因素和其它因素造成的潜在瓦斯喷出的危险性,注定了喷出按一定的规律发生。瓦斯喷出存在各种各样的构造破坏影响带附近,喷出的表现形式多种多样,不同的矿床具有不同的喷出规律和深度。总之,掌握深 Gas ejection is a dynamic phenomenon occurred in the geological body during the deep excavation of coal mines. The geological conditions play a decisive role in the factors that cause the gas emission tendency. On the other hand, due to the extractive production activities, that is, the interference and destruction of the rock mass balance state, the danger of potential gas emission caused by geological factors and other factors is caused and the discharge is destined to occur according to a certain rule. There are a variety of tectonic damage caused by gas ejection in the vicinity of the impact zone. There are many kinds of gas ejection features. Different deposits have different rules and depth of discharge. In short, grasp the depth
