科学论证,煤炭生产的发展实践均已证明沿空留巷是缓解紧张的采掘接续的一个重要技术环节,也是在煤矿生产中应用较广的一种新的护巷方法;它利于煤炭资源的回收、降低巷道掘进率、还可消除因留煤柱引起的井下灾害。沿空留巷已成为实现无煤柱开采的主要技术措施之一,被我矿工程技术及管理人员越来越重视,但沿空留巷这种工艺在实际应用中仍有许多技术方面问题有待更进一步探索、研究。
Scientific demonstration and practice of coal production have all proved that gob-side entry retaining is an important technical link in alleviating the intense mining continuation and a new method of laneway protection that is widely used in coal mine production. It is conducive to the recovery of coal resources , Reduce tunneling rate, but also eliminate the coal mine column caused by underground disasters. Gob-side entry has become one of the main technical measures to realize non-coal pillar mining. It has been paid more and more attention by mine engineering technology and management personnel. However, there are still many technical problems in the practical application of Gob-side entry retaining technology Further exploration, research.
