摘要
疏降第四系底部含水层提高开采上限是煤矿安全生产和最大限
度的开采地下煤炭资源的有效方法之一。本文从水文地质学、工程地
质学、开采沉陷学、勘察工程学、采矿工程学等多学科联合交叉的角
度，在太平煤矿钻探、物探等各种勘探资料基础上，分析上覆岩土体
的工程地质条件，建立工程地质模型，并以8301工作面为研究对象，
进行工程地质力学模型实验，对覆岩破坏规律和开采的安全程度进行
了研究，综合各种结果获得了太平煤矿近风化带覆岩破坏的高度;在
水文地质条件分析基础上，参考国内外疏降开采的成功实例，探讨了
难疏放含水层的疏放技术，并推求出不同土层在覆岩破坏带不发生溃
砂的安全水头高度。开采实践和实测证明了研究结果的正确可靠。
