无煤柱开采是合理开发利用煤炭资源、提高回采率、降低掘进率、减少巷道维护费、提高经济效益的有效技术措施,它是回采工艺的一项改革。因此,在一定条件下的煤层中,应积极推广无煤柱开采技术,为推进和实现安全、高效矿井提供有利的保证。
Pillarless mining is an effective technical measure to rationally develop and utilize coal resources, increase recovery rate, reduce driving rate, reduce roadway maintenance fee, and improve economic efficiency. It is a reform of the recovery process. Therefore, under the condition of coal seam, non-pillar mining technology should be actively promoted to provide a favorable guarantee for the promotion and realization of safe and efficient mines.
