Study on Optimization of Fast Tunneling Technology in Complex Geological Coal Mine

针对当前煤矿复杂地质情况遇见的采掘过程中的支护问题,研究了一种基于滞后迎头分级弱化的支护技术的快速采掘工艺,该工艺参考煤矿的具体地质环境,对传统的支护工艺进行优化提升,通过对5组支护工艺的模拟,最后得出其中最佳的支护方案,并对当前煤矿的支护工艺进行优化。为解决快速掘进问题提供一种借鉴思路。

In view of the support problems encountered in the mining process under the complex geological conditions of the current coal mine,a fast mining process based on the support technology of lagging head-on grading weakening is studied.The process refers to the specific geological environment of the coal mine,optimizes and improves the traditional support technology.Through the simulation of five groups of support technologies,the best support scheme is obtained,and the current coal mine support technology is optimized.It provides a reference for solving the problem of rapid tunneling.
