项目采用理论分析、数值模拟、现场实测等多种研究手段,对锚杆支护巷道顶板离层界限值进行研究,提出了“广义顶板离层”和“狭义顶板离层”的概念。并利用顶板离层仪及时准确地掌握煤巷锚轩支护顶板板离层情况。
In this project, theoretical analysis, numerical simulation and field measurement are used to study the demarcation of roof delamination in bolt supported roadway. The “generalized roof delamination” and “narrow roof delamination” are proposed. concept. And the use of roof delamination instrument timely and accurate grasping coal seam anchor Xuan roof board separation situation.
