摘要
介绍了我国沿空留巷巷内和巷旁支护形式及其理论研究现状,分析了沿空留巷的适用条件,指出了我国沿空留巷目前所存在的主要问题是支护设计思路不合理、巷内支护多属于被动支护、巷旁支护存在力学性能与沿空留巷围岩变形不适应、对沿空留巷围岩控制机理研究不够深入。并提出了将沿空留巷技术视为一项系统工程、采用锚网索支护作为沿空留巷内基本支护等发展沿空留巷技术的建议。
The paper summarized and introduced the support mode in the mine gateway and at the side of the gateway and the theoretical study status for the gob-side entry retaining. The paper analyzed the suitable condition for the gob-side entry retaining. The paper pointed that the main problems existing in the present gob-side entry retaining in China were the irrational support design ideal, support system in the mine gateway being passive support, the gateway side support with unsuitable between the mechanics performances and the surrounding rock deformation of the gob-side entry retaining and the les deep study on surrounding rock control mechanism of the gob-side entry retaining. The paper pointed that the gob-side entry retaining technology should be a system project, the bolt/steel mesh and anchor combined support should be as the basic support for the gob-side entry retaining and the proposals on the development of the gob-side entry retaining technology.
