超前预留缓冲区交替式相向采掘沿空送巷的应用研究

Study on the Application of the Alternative Phase Mining with the Pre Reserved Buffer Zone

为了减少工作面推采产生的矿压对沿空送巷的影响,采用预留采掘头面之间的安全缓冲区和合理避开矿压应力区,预留缓冲区交替式相向采掘工艺,实现矿井沿空送巷高效安全生产。

In order to reduce the influence of the mine pressure produced by the push mining of the working face on the driving roadway along the goaf,the safe buffer zone between the mining heads and faces and the reasonable avoidance of the mine pressure stress zone are adopted,and the alternate opposite mining technology of the reserved buffer zone is adopted,so as to realize the efficient and safe production of the driving roadway along the goaf.
