Abstract:

Based on the actual survey, it is found that because the road along the reservoir bed that is dug in the thick coal bed when subjected to the impact of mining is deformed and destroyed, to keep the furnace bent, the brace will be bent and pulled, and the rock between the anchors is strongly lashed, destroying the reinforcing arch causing the furnace to collapse. In their research, the authors focus on research to make new brace that enhance the ability to work with anchors and anchors, keeping the furnace stable. Through a comprehensive analysis of the constraints of the existing tie rod, It is proposed that the new brace bears a horizontal cross section of JW, using ANSYS software to test the JW brace performance. The results show that the JW brace meets the requirements, overcome the limitations of the brace is used. The results of this study may be a reference for scientists in the design and construction of brace
