摘要
根据现场工程地质条件调查分析、岩石物理力学特性和复合顶板大断面综采切眼围岩力学变形机制及其转化研究,提出了复合顶板综采工作面巷道锚网锚索耦合支护设计方案。施工结果证明其在技术上是可行的,安全上是可靠的,经济上是合理的。
Accounting to the investigation and analysis of the field engineer in g geological conditions, the physical and mechanical characteristics of the rock s, and the research on the mechanical deformation system and transformation of t he wall-rocks of the comprehensive mechanized coal mining's cut hole with large section of the composite roof, this paper puts forward the design scheme of the anchor rope and anchor net supporting for the working face of the comprehensive mechanized coal mining under the composite roof. The results of the constructio n certify that the technique is feasible in technique, reliable in safety, and r ational in economy.
