富力矿暗井绞车硐室支护方式浅议

Discussion on Supporting Methods of Staple Big Section in Fuli Colliery

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。

Aiming at length of service and enclosing lithologies of chamber, the paper analyzed the forces of chamber and calculated its supporting parameter according to combined arch theory. The combined supporting structure of ＂Anchor net, band, the combined supporting of bolt＂ was adopted in underground large cross section chamber, which achieved better technical economic effect.
