摘要
为了预防矿井复采时发生水害事故,对新丰煤矿水文地质资料及井上下物探成果资料进行分析,确定了矿井老空水害分布特征及范围,研究探索了一整套老空水综合防治技术体系。实践应用表明,老空水综合治理体系的使用成功消除了矿井水害,解放了呆滞煤量,保证了安全生产。
To ensure the water inrush accidents not to occur in coal mine remining,through the analysis of hydrogeological information of Xinfeng Coal Mine and the results of geophysical expIoration on surface and underground of coal mine,the distribution characteristics and the scope of mine goal water haszards were determined, a technology system of comprehensive goal-water prevention was studied and proposed. Results show that,the application of comprehensive goal-water prevention system successfully eliminates the water hazard,lib- erate dull coal reserve, and ensure the safe production.
