Research on Surrounding Rock Stability Analysis and Support Optimization for Deep Coal Mine Mining Engineering

摘要

深部煤矿采矿工程中，围岩稳定性是确保矿山安全和提高生产效率的关键因素。随着矿山深度的不断增加，围岩稳定性面临更大的挑战。围岩的破坏和变形直接影响到采矿过程的安全性及支护系统的设计。本文通过分析深部煤矿围岩稳定性影响因素，包括地质条件、开采方式及围岩的物理力学性质等，探讨了围岩变形与破坏机制。通过应用多种稳定性评价方法，结合实际矿山数据，评估了不同支护技术对围岩稳定性的影响，并提出了支护优化设计方案。研究为深部煤矿采矿工程的支护设计提供了理论依据和技术支持，有助于实现煤矿采矿的可持续发展。

Abstract

In deep coal mining engineering,the stability of surrounding rock is a key factor in ensuring mine safety and improving production efficiency.As the depth of mining continues to increase,the stability of surrounding rock faces greater challenges.The destruction and deformation of surrounding rock directly impact the safety of the mining process and the design of the support system.This paper analyzes the factors influencing surrounding rock stability in deep coal mines,including geological conditions,mining methods,and the physical and mechanical properties of surrounding rock,and explores the mechanisms of surrounding rock deformation and failure. By applying various stability evaluation methods and combining actual mine data,the paper assesses the impact of different support technologies on surrounding rock stability and proposes an optimized support design plan.The research provides theoretical basis and technical support for the support design of deep coal mining projects,contributing to the sustainable development of coal mining.
