摘要
煤与瓦斯突出极易在石门揭煤过程中发生,突出事故一旦发生,将摧毁巷道设施、通风系统,使矿井内充满瓦斯与煤粉,造成瓦斯窒息,威胁作业人员人身安全。当地质条件较复杂、矿井技术水平不高的小型矿井,在石门揭煤时应施工超前探孔、排放孔、揭煤前后加强支护的技术措施,从而保证石门的安全揭煤。该揭煤技术现场技术人员易掌握,施工方便、揭煤成本较低。
Coal and gas outburst is apt to happen in the process of rock cross-cut coal uncovering. Once the accident happens, it will destroy the roadway facilities, ventilation system, so that the mine is full of gas and coal, resulting in gas suffocation, threatening the safety of personnel. When the geological conditions are more complex, and the mine is in small-scale, during thecross-cut coal uncoveringthe probe hole and discharge hole work should be done before construction to strengthen the support before and after uncovering the coal for ensuring the safety of rock cross-cut coal uncovering. This coal mining technique at low cost of coal uncovering is easy to grasp and convenient to apply.
