摘要:

为了提升采矿工程中巷道的稳定性与安全性,在历经国内外近60a的研究与不断优化过程中,关于沿空留巷及巷道围岩控制的理论与实践已经积累了丰富的成果。本研究深入剖析了在不同开采模式中沿空留巷的应用情况,并详细阐述了表面支护、锚固、改性、卸压及联合控制五种关键的沿空留巷围岩控制技术。在此基础上,进一步探讨了充填式与切顶式沿空留巷的适用场景。特别地,在充填式沿空留巷的实践中,通过对比其他充填材料和方式,深入分析了高水材料的独特性质及其在充填过程中的应用特性,并研究了该技术的施工工艺,包括材料配比和充填方式方法等关键要素。实验与现场数据充分证明,高水材料充填技术能够有效强化巷道的结构强度,显著降低安全事故的风险,并显著提升煤炭资源的回收率。

Abstract:

In order to improve the stability and safety of roadway in mining engineering, after nearly 60 years of research and continuous optimization at home and abroad, the theory and practice of lining roadway and surrounding rock control have accumulated rich achievements. This paper deeply analyzes the application of lining roadway in different mining modes, such as forward, regressive and reciprocating mining. At the same time, it elaborates on the five key surrounding rock control technologies of lining roadway, namely surface support, anchorage, modification, pressure relief and joint control. On this basis, the paper further discusses the application scenarios of filling and top-cutting lining roadway. In particular, in the practice of filling lining roadway, by comparing with other filling materials and methods, the unique properties of high water material and their application characteristics in the filling process are deeply analyzed. Experiments and field data fully prove that the filling technology of high water material can effectively strengthen the structural strength of roadway, significantly reduce the risk of safety accidents, and significantly improve the recovery rate of coal resources. In addition, this paper also studies the construction technology of this technology, including the key elements of material proportioning and filling methods. The research provides important guidance for the practice of mining engineering, and lays a foundation for the further development of this technology.
