摘要
为了解决四台矿开采下部煤层时工作面回采巷道复合顶板特殊条件下掘进支护难的问题。通过对该矿巷道掘进过程中的动压特征分析和高应力作用下采取支护措施的效果研究,取得了复合顶巷道受层间距小、过应力集中区域、动压影响大等条件下的巷道掘进支护与加固技术经验。
In order to solve the heading and support difficulties under the special conditions of the complex roof in the mining gateway of the coal mining face in Sitai Mine,a research on the analysis of the dynamic features during the typical gateway heading process and the support measures under the high stress was conducted.The experiences of the gateway heading,support and reinforcement technology were obtained under the conditions of the short distance between the strata,stress concentrated area and high dynamic...
