底角锚杆控制巷道底臌的数值模拟
Numerical simulation of floor heave with corner anchor control
摘要
Abstract
Aimed at seeking an effective method of controlling increasingly serious floor heave arising from greater mining depth, this paper describes the use of numerical simulation method to analyze the deeper roadway under the stress due to bottom anchor application. The results show that the application of bottom anchor in roadway floor results in transference of the stress to the deeper area of roadway, less in- fluence of rock stress on floor, and less deformation of roadway. Both numerical simulation and practical application prove that, the bottom anchor-controlling technique, when used in areas with suitable condi- tions, affords an effective solution to floor heave.关键词
