摘要
受采空区积水影响,邻近工作面在回采期间出现透水现象,不仅影响着工作面正常回采,而且采空区水压加大很容易破坏保护煤柱,发生重大煤矿透水事故。对此,潞安集团司马煤业公司1207工作面在回采期间对邻近采空区积水采取合理有效的探放水措施,确保了工作面安全稳定回采。
Under the infuence of the water accumulation in the goaf area, the phenomenon of water permeation in the adjacent working face during the mining period not only affects the normal mining of the working face, but also increases the water pressure in the goaf area, which is easy to damage the protective coal pillars and lead to major coal mine water permeation accidents. In this regard, reasonable and effective measures were taken to detect and release the water in the adjacent goaf during the mining in the working face of Sima Coal Industry Company, Lu’an Group, to ensure the safe and stable mining in the working face.
