Coupling Support Design for Deep Pit Bottom in No.5 Coal Mine of Hebi Coal Industry Group and Its Application
摘要
Abstract
In order to solve the support difficulties of deep soft rock roadways in No. 5 Coal Mine of Hebi Coal Industry Group, taking the extending pit bottom engineering of Horizon 3 in the mine as an example, we analyzed the geological conditions and characteristics of surrounding rock, and evaluated the deep engineering difficulties firstly, by means of the field geological investigation, laboratory test, theoretical analysis, numerical simulation and on-site monitoring. The type of the roadway surrounding rock is determined to be high stress-jointed-swelling soft rockmass, with Ⅰ ab Ⅱ abd Ⅲ ae compound deformation mechanical mechanism, according to the theory of soft rockmass engineering mechanics. Then the corresponding control counter-measures were analyzed by theoretical analysis and numerical simulation. Finally, the specific coupling support modes and parameters, and the appropriate construction process were put forward. The field construction and monitoring results show that the coupling support design composed of bolt- shotcrete-mesh-cable, base angle grouting bolt, and flexible layer truss, can effectively control the large deformations of deep soft rock roadways in the mine and ensure the long-term stability and safety operation of the roadways.关键词
