对宁东煤田某矿011801工作面的水文地质条件特别是风氧化带进行了分析,总结了矿井011802工作面风氧化带突水溃砂灾害的形成机理,对011801工作面涌水量进行了合理的预计,经济合理布置了探查钻孔对风氧化带水进行了有效防治,提出了工作面近风氧化带安全回采所必备的条件和水文地质工作程序,在011801工作面实际安全回采中得到了应用和证实。 This paper analyzes the hydrogeological conditions, especially the wind oxidation zone, of the 011801 working face of a mine in Ningdong coalfield, summarizes the formation mechanism of the wind-oxidation zone water-bursting sand-collapse disaster in 011802 working face, and makes a reasonable It is estimated that the economic and reasonable arrangement of the exploration borehole for the effective prevention and treatment of the wind oxidation zone water and the necessary conditions and hydrogeological procedures for the safe recovery of the near-wind oxidation zone in the working face are proposed. The actual safety recovery of the 011801 face is obtained Apply and confirm.
