摘要
巷道掘进质量作为影响矿井生产综合效益的重要因素,确保其支护的有效性对矿井生产安全意义重大。以此为着手点,针对大断面煤巷掘进支护技术开展分析探究。结合具体工程实际,在分析巷道原支护体系破坏原因的基础上,开展支护方案优化探究,并对优化后方案应用效果做出分析。结果表明,优化后的支护方案实现了对巷道围岩变形的有效控制,为巷道的长期安全使用提供了有力保障。
The roadway driving quality is an important factor influencing the comprehensive benefits of mine production.So it is of great significance to ensuring the effectiveness of its support for mine production safety.Taking this as a starting point,analysis and research on the support technology of coal roadway with large section were carried out.Combined with the actual engineering,and on the basis of analyzing the reason of original support system damage of the roadway,this paper carried out the optimization research on the support plan,and made an analysis of the application effect of the optimized plan.The results showed that the optimized support scheme realized effective control of the deformation of the surrounding rock of the roadway,and provided strong guarantee for the long-term safe use of the roadway.
