| 摘 要： | 以新疆伊犁四矿为研究对象，对21103工作面21-1煤厚煤层在浅埋深薄基岩条件下综放开采的防溃砂技术进行了研究，通过对煤层顶板含水层赋存规律进行总结分析，根据含水层的赋存特征对工作面进行块段式划分，提出了以控制覆岩破坏发育高度为主要原则的限厚开采方案，实现了矿井的安全开采。

| Abstract: | This research selected the Yili No.4 Coal Mine of Xinjiang as the study object，to carry out research on the technology of preventing inrush of sand of shallow buried thick 21-1 coal seam in working face of 21103 for fully-mechanized caving mining.The occurrence regularity for roof aquifer of coal seam was summarized and analysed，and the working face was divided into blocks and sections according to the occurrence characteristic for aquifer.This study comes up with the mining scheme of limited thickness extraction，which achieved the safe mining of the coal mine. |
