夹河煤矿针对深部复杂条件高瓦斯开采特点,采取了煤壁区、材料巷顶板控制技术、过断层、过异常区技术,有效保证了深部高应力下的三软煤层安全高效回采;采用了以瓦斯抽放为主的综合治理瓦斯措施,加大工作面供风量,稀释瓦斯,达到综合治理瓦斯的目的;通过简化通风系统,适当加大工作面供风量等手段,改善采场气候条件,解决了地热危害。
In view of the characteristics of high-gas exploitation in complex conditions in deep river, Jiahe Coal Mine adopted the technology of coal wall area, material roof control, over-fault and over-anomaly to effectively and safely ensure the safe and efficient mining of three soft coal seams under high stress. Gas drainage, comprehensive management of gas measures, increase the work surface air supply, dilution gas, to achieve the purpose of comprehensive management of gas; by simplifying the ventilation system, appropriate increase the work surface air supply and other means to improve stope climatic conditions, to solve Geothermal hazards.
