摘要
以刘家沟井田水文地质资料为基础,分析研究了井田水文地质条件、矿井充水水源及充水通道,采用大井法和集水廊道法对矿井涌水量进行了预测。经比较,大井法计算结果更准确,先期开采地段矿井正常涌水量为365.94 m3/h,全井田矿井正常涌水量为788.08 m3/h。预测结果为该矿井水害防治和安全生产提供了科学依据。
Based on the hydrogeological data of the Liu Jiagou minefield, the hydrogeological conditions of the minefield,source of water inrush and the water-filling channel were analyzed and studied. With the methods of big-shaft and catchment corridor, the mine inrush water was predicted. The result of catchment corridor method was more accurate,pre-mining area was 365.94 m3/h and minefield was 788.08 m3/h. It offered a scientific basis for prevention and control of water disasters of mine and production safety.
