顶板砂岩水下开采大水工作面水害综合防治

Integrated control of water disaster in flood working face of underwater mining in sandstone roof

矿井水害复杂多样,在煤炭开采过程中,煤层构造(断层)导水、陷落柱导水、含水层(体)出水等均有可能造成灾害事故。运用物探、钻探相结合的综合探测、超前疏放水方法,配合科学有效的防排水系统,防治煤矿水害的优势明显。高分辨震波勘探、电法勘探等综合物探技术和导水漏斗、过水溜槽、铁槽水沟、振动筛、沉淀池组合应用,可有效防止地质构造、陷落柱、含水层等含水体突水事故及达到煤水分离保证中央泵房排水安全的效果,从而实现工作面安全生产,对促进煤矿的安全生产具有重要的意义。

Based on various mine water disasters caused by coal seam structure （fault） water diversion, collapsing column water transmitting and aquifer （body） water in the process of coal mining, combining with scientific and effective watertight and drainage system, advanced drainage method and integrated detection of geophysical prospecting and drilling were used, which showed obvious advantages of prevention and control of coal mine water hazards. Integrated geophysical prospecting technique of high resolution seismic exploration and electrical prospecting, together with combined application of water guide funnel, water chute, vibrating screen and setting pond could effectively prevent water inrush accident of geologic structure, collapse column and aquifer, assure the safety effect of coal water separation to central pump room drainage to achieve safety production of working face, which made a difference in safety production of coal mine.
