1、 摘要摘要 协庄煤矿现已开采到第四水平, 并且该水平所剩储量日趋减少, 因此 第五水平延深是亟待解决的重要问题。 本论文设计时, 充分考虑了矿井延深部分的地质情况, 并且最大限度 的利用原有的井巷和设备。 开拓方案和采区准备方案, 都经过了技术和经 济比较,选出了自己认为优越和合理的方案,延深和准备方案细节如下: 开拓方式选用两条暗斜井延深; 运输采用集中运输大巷, 采区内煤层采用 联合布置,二、四、六为前组煤,十一、十三、十五为后组煤;采煤方法 为走向长壁后退式开采; 工作面顶板用液压支架支护, 采用全部跨落法管 理顶板;运煤采用 3t 底卸式矿车和皮带混合运输;通风方式为中央分列 式。 在
2、论文中还提到了预防安全隐患的措施, 各大系统都能满足安全和生 产的要求。 关键词:关键词:开拓延深 斜井延深 联合开采 ABSTRACT Coal mining is now Xiezhuang to the fouth level, and the level of remaining reserves to reduce the growing, the level of the fifth extension is an important issue to be resolved.
