    Study on mining technology of overlying goaf and empty roadway with shallow buried fully mechanized mining face

    • 摘要: 以补连塔煤矿12424综采面为例,对浅埋综采面过上覆采空区及空巷回采技术进行研究。具体通过综采面矿压观测、综采面进出上覆采空区生产情况、综采面过上覆空巷,以及过顺槽超高度段等特殊条件的回采情况进行总结,详细分析了初次来压、周期来压及特殊地质条件下的来压情况,对类似综采面回采有指导意义。

       

      Abstract: Taking the 12424 fully mechanized mining face of Bulianta Coal Mine as an example, this paper investigates the mining technology of shallow buried fully mechanized mining faces passing through overlying goaf and empty roadway. Specifically, through the observation of mining pressure on the fully mechanized mining face, the production situation of entering and exiting the overlying goaf on the fully mechanized mining face, and the mining situation under special conditions such as passing through the overlying goaf and over height sections of the inclined groove on the fully mechanized mining face, a detailed analysis is conducted on the initial pressure, cyclic pressure, and pressure under special geological conditions, which has guiding significance for similar mining on fully mechanized mining faces.
