摘要
根据硐室的服务年限及围岩岩性,分析了硐室的受力情况,依据组合拱理论计算出支护参数。在井下大硐室采用“锚网带、喷+锚索”联合支护结构,取得了较好的技术经济效果。
According to the service life limit of stone room and sun.unding rock. the circumstances of bearing force are analyzed. On basis combination arch theories, the support parameters are computed. Applying anchor and net shotcreting and anchor rope combined support structure has obtained good technique result.
