分析切顶卸压沿空留巷动压承载临时支护技术

Analysis of Temporary Support Technology for Dynamic Pressure Bearing of Roadway Along Goaf with Roof Cutting and Pressure Relief

本文重点针对切顶卸压沿空留巷在特殊开采范围内收到的压力影响进行了分析和阐述,重点提出了使用动压承载,临时支护的方法来对整个压力的影响进行有效的控制,有效防止巷道顶板出现不良变形问题。通过理论计算和分析,对动压承载临时支护的作用原理进行了阐述,并且得出了该支护方式对顶板岩层回转下沉所产生的控制性作用,为整个煤矿创造的稳定性打下了良好的保障。

This paper focuses on the analysis and elaboration of the influence of the pressure on the roadways along the goaf in the special mining area, and puts forward the method of using dynamic pressure bearing and temporary support to effectively control the influence of the whole pressure and effectively prevent the tunnel roof from bad deformation. Through theoretical calculation and analysis, this paper expounds the working principle of the dynamic pressure bearing temporary support, and obtains the controlling effect of the support mode on the rotary subsidence of the roof strata, which lays a good guarantee for the stability created by the whole coal mine.
