摘要
王河煤矿是荥巩矿区涌水量最大的煤矿,涌水量2100-2400m^3/h^[1],建矿以来共发生突水20余次,突水量9-1200m^3/h,严重影响煤矿的安全生产。王河煤矿主采煤层为一。煤,充水来源主要受奥灰水的影响。通过瞬变电磁勘探查明了111070工作面煤层底板以下50m范围内奥灰赋水性情况、富水区范围及导高位置,根据瞬变电磁勘探成果,在111070工作面进行井下注浆堵水,突水量减少了80%以上,为矿井安全生产提供了保证,为王河煤矿及同类矿井水害防治提供了有益的借鉴。
Wanghe Coal Mine is the biggest coal mine in Xingyang welling up water volume 2100-2400m^3/h^[1]. Since its construction , it has flooding 20 times, flooding quantity 9-1200 m^3/h. It influences the safety of coal mines in production. The Wanghe coal mine main mining coal level is a-1, Is filled with water the origin mainly the Austria buck influence. This paper verifies 109020 working surface earth through the transient electromagnetism exploration in the 50m scope. According to transient electromagnetism exploration achievement, the well bottom pouring thick liquid water shutoff in 111070 working surfaeesis carried on. The flooding quantity is reduced by 80%.
