摘要 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。 Analyzed the hydrogeological conditions of 011801 working face of a mine in Ningdong coal field, especially the hydrogeological conditions of 011802 working face efflorescent oxygenized belts.The formation conditions of inrush of water and sand in efflorescent oxygenized belts were summarized.Then the quantity of water inflow for 011801 working face was reasonably expected and the bore holes were arranged economically and reasonably for water exploration so as to control the water in efflorescent oxygenized belts. The necessary conditions and working procedures for safe mining approaching to efflorescent oxygenized belts were applied in 011801 working face and proved to be effective.
