沿空掘巷技术能够较好地实现无煤柱护巷,它是煤矿开采技术的一项重大改革,此项技术不仅是合理开发煤炭资源、提高煤炭资源采出率、延长矿井服务年限、减少巷道掘进量、缓解裁决接替矛盾、取消孤岛工作面及缩短搬家时间、防止发火、有利于矿井安全生产和改善矿井技术经济效果的一项重大的护巷技术,而且它也是矿山进行采煤方法改革、实现前进式和往复式开采、治理工作面瓦斯超限难题的最有效途径,其技术优势和经济效益显著。
Gob-side entry driving technology can realize coal pillar-free roadway protection. It is a major reform in coal mining technology. This technology is not only a reasonable development of coal resources, improve the recovery rate of coal resources, extend mine service life, reduce Roadway excavation volume to ease the decision to take over the contradictions and cancel island work surfaces and shorten the moving time to prevent ignition, is conducive to mine safety production and improve the technical and economic efficiency of mine a major roadway protection technology, and it is also the mining method of mining reform , The most effective way to realize progressive and reciprocating mining and to control gas overrun problem in workface is obvious, with its technical advantages and economic benefits.
