沿空留巷技术研究现状与展望

Research Status and Development Direction of Gob-side Entry Retaining Technique

实现我国煤矿可持续发展的关键在于合理开采、利用现有煤炭资源、提高资源回采率。沿空留巷技术在理论和实用价值层面促进了无煤柱护巷技术的发展,技术经济优势明显,符合绿色采矿、科学采矿的发展思路。为此,详细分析了沿空留巷理论研究、支护形式的国内外研究现状,剖析了该技术的应用成果,探讨了该技术的发展方向,为沿空留巷技术的快速发展提供参考。

The keys of the efficient and sustainable development in coal mines in our country is reasonable exploitation,utilization of the existing coal resources and improvement of resources stoping rate.The development of roadways protection without coal pillars technique is promoted by the god-side entry retaining technique in the aspect of theoretical and practical value,and it has obvious technical and economic advantages,besides that,it is consistent with the development thought of scientific mining and green mining. In order to better understand the technique,the development status of domestic and foreign of the god-side entry retaining theory and god-side entry retaining technique are analyzed in detail,the results obtained during the application process of the god-side entry retaining technique are discussed in depth,based on the above analysis results,the development direction of the god-side entry retaining technique is studied to provide reference for the development of the god-side entry retaining technique.
