松脆围岩炮采工作面沿空留巷技术研究

Research on Technology of Gob-Side Entry Retaining on Crisp Surrounding and Blasting Face

为提高新庄矿煤炭资源回收率,延长矿井服务年限,缓解采掘接替紧张状况,提出了一种基于松脆围岩炮采工作面巷旁充填新型高水速凝材料的沿空留巷技术,研究结果表明留巷效果较好。

In order to improve the recycle rate of coal resources, extend the service-life of the mine, and alleviate the tensions of excavation-replacement in the Xinzhuang mine,presents a high-water material for roadside packing to go with gob-side entry-retaining technology on crisp surrounding rock and blasting working face. The results show that the construction achieves a more satisfactory effect.
