新密西区煤矿群带压开采条件下水灾害综合治理

Comprehensive control of water disasters about coal minegroup under pressure conditions in the west region of xinmi

为了研究带压开采条件下煤矿群水灾害综合治理技术,通过数值模拟确定了底板"下三带"的高度,为防治底板突水提供定量数据;运用多维协同预测预报技术,使预报的准确性大大提高;采取多种疏放措施,有计划、有步骤地进行主动疏放,同时对突水点及时应用注浆封堵技术,新密西区煤矿群水灾害治理效果明显.

This paper studied the comprehensive control of water disasters technology under the pressure conditions of mining coal mine group, determined the height of base ＇down three zones＇ through the numerical simulation, and provided the quantitative basis for water inrush prevention floor. With the multidimensional prediction techrlologv of collaborative, forecasting, the forecasting accuracy is greatly impiroved; By taking various drainage measures and having a pratical plan and steps in the active drainage process, and timely application of grouting technology for water inrush point, the effectiveness of ground water disaster control in Western Xinmi coal mine group is obvious.
