摘要
依据巷道围岩地质条件,计算了运输大巷围岩破碎区、塑性区范围,给出了合理的锚杆支护参数,并结合数值模拟对支护参数进行模拟验证,确定的方案能够有效保证巷道的整体稳定性,具有良好的社会经济效益。
According to the geological condlhons ot surrounumg rock in roadways, the range ofsurrounding rock broken and plastic area in the main haulage roadway is calculated, the correct parameters of bolt supporting is obtained, and support parameters is simulated combined with the numerical simulation, the scheme can effectively guarantee the global stability of roadways and get fine society and economy benefits.
