Abstract

ABSTRACT This study focuses on addressing the issues of spontaneous combustion and slope instability at the coal mine waste (CMW) dump located on the north side of the Yumen River in Ximing Mine, China. We conducted slope restoration and environmental treatment of the CMW dump using shotcrete, deep hole grouting, external soil spray seeding technology with multiple soil fixation measures. The stability of the repaired CMW dump was analysed using LiZheng Slope Stability Analysis Software, and the displacement and stress of high-risk zones were assessed using MIDAS GTS NX Software. Our findings provide valuable insights for slope restoration and evaluation.

煤矿排土场生态修复研究——以西明煤矿为例

摘要本研究针对西明煤矿玉门河北岸煤矿矸石排土场自燃和边坡失稳问题进行了研究。采用喷射混凝土、深孔灌浆、外喷土播种等多种固土措施对CMW排土场进行边坡修复和环境治理。利用LiZheng边坡稳定性分析软件对修复后的CMW排土场进行稳定性分析，利用MIDAS GTS NX软件对高危区进行位移和应力评估。我们的研究结果为边坡恢复和评价提供了有价值的见解。
