| 摘 要： | 济宁何岗煤矿一采区3煤在风化氧化带内，对其开采的防水防砂基本技术思路是：施工水文观测孔，观测回采后对第四系下组含水层的影响程度，为提高开采上限打好基础；并控制采高，加强顶板管理，控制顶板在工作面斜长方向上的不均匀冒落，以确保安全开采。

| Abstract: | Third coal stratum of Hegang coal mine occurs in weathering and oxidation belt.Basic technical thoughts for preventing water and sand during mining period are as follows: building hydro-observation well,observing effect degree to Quaternary water-bearing layer after stoping,setting a good basis for promoting mining upper bound,controlling mining depth,strengthening roof management,and controlling differential roof collapse in oblique backwell.Thus, safe mining can be guaranteed. |
