综放工作面过空巷工艺的实践和探讨

Practice and Probe into Passing through Abandoned Roadway Technology in Fully Mechanized Caving Face

介绍了阳煤集团一矿8710工作面过5条围岩破碎条件复杂的空巷的成功实践,通过采取提前加强支护,过空巷期间工作面及时调整,破碎煤体注浆加固等一系列有力措施,有效的维护了顶板的安全,确保了过空巷期间的安全生产。也创造了巨大的经济效益,为相同条件工作面过空巷提供了技术支持和经验参考。

The paper introduced the successful practice of passing through 5 abandoned roadway with complex crush conditions at8710 face, No.1 Colliery, Yangquan Coal Industry Group Co., Ltd. A series of powerful measures such as strengthening support in advance, timely adjusting face during passing through abandoned roadway and grouting reinforcement broken coal, etc. have been taken, which effectively maintained roof safety, ensured safety production during passing through abandoned roadway, created huge economic benefits and provided technical support and experience reference for passing through abandoned roadway in face of similar conditions.
