针对我矿32213(1)工作面回风顺槽施工瓦斯抽放硐室工艺进行优化,结合结合汝箕沟煤矿掘瓦斯抽放硐室机械化施工情况,基于围岩变形与移动原理、工作面支护原理、掘进机性能,合理改变瓦斯抽放硐室的形状,对瓦斯抽放硐室快速安全掘进方案进行分析论证,提出了合理的掘进工艺提出掘进机施工瓦斯抽放硐室.确保了施工安全,优化了了实际工作中的难题,为综采工作面的回撤起到了重要作用,同时也节约了大量资金.
In view of the optimization of gas drainage chamber technology for the construction of 32213 (1) working face in the mine, combined with mechanized construction of digging gas drainage chamber in Rujigou Coal Mine, based on the deformation and movement principle of surrounding rock, Protection principle and performance of roadheader, reasonably change the shape of gas drainage chamber, analyze and prove the fast and safe boring program of gas drainage chamber, put forward a reasonable tunneling technology to propose gas drainage chamber for roadheader construction, ensure the construction Safe and optimized the difficult problems in practical work, which played an important role in the pullback of fully mechanized mining face and also saved a lot of money.
