摘要
针对我国井工矿井巷道掘进工程量大且支护困难的实际情况,在理论分析支护与围岩相互作用关系的基础上,进一步分析了支护补偿作用原理、工字钢棚结构受力和锚网索支护作用,研究结果对选择合理支护方案具有一定参考意义。
Aiming at the actual situation of large amount of mine roadway excavation and difficult support in China, based on the theoretical analysis of the interaction between support and surrounding rock, the principle of support compensation and the force of I-steel structure are further analyzed. The anchor net support effect, the research results have certain reference significance for the selection of reasonable support scheme.
