Application of Unequal Strength Partition Reinforcement Technology in Complex Slope Protection

In order to solve the difficult problem of falling, dumping and slump of complex slope around Baode Coal Mine, by analyzing the complex geological conditions and the nature of the surrounding rock slope, we study the damage and deformation characteristics of slope at different regions, and divide slope area, and innovatively propose unequal strength partition reinforcement and supporting technology for the mining slope protection. The field monitoring data show that maximum horizontal displacement of the slope in different areas is 46 mm after adopting the reinforcement scheme, just 0.35 times compared with before reinforcement. So, using the slope protection scheme can control the slope deformation economically and effectively, it ensures the safe and efficient production of coal mine and surrounding environment repair.
