中文摘要：

以海石湾矿深井油页岩工作面无煤柱开采为工程背景,研究深井厚煤层的沿空留巷围岩稳定性问题.提出了高预应力、适应沿空留巷大变形基础支护和高支撑阻力、可控制沿空留巷顶底板剧烈变形的巷内加强支护的巷内支护体系,以及高强度、快速增阻、可缩性好的巷旁充填体和良好的充填区域顶板维护的巷旁支护体系.研究成果可为类似条件下沿空留巷提供参考.

英文摘要：

Taking non-pillar mining face with oil shale surrounding rock in Haishiwan Mine as the enginenring background,the surrounding rock stability of deep mine gob-side entry retaining with thick seam is analyzed. The control theory of surrounding rock is proposed,namely the high prestressed bolting support suited to large roadway deformation,the high support resistance secondary support which can control the roof and floor deformation,the high strength roadside packing wall which has fast increasing resistance and good solubility,and outstanding roadside roof supporting techniques. Results are of references for the similar engineering specifications.
