Abstract: This paper takes Xiushuihe mine as the engineering project, the formed H2 landslide as theresearch object, and evaluates the stability of three conditions ( the natural state, rainstorm and earthquake) by using the transfer coefficient method. Based on the analysis of the formation mechanism of thelandslide , the paper puts forward the prevention and control scheme of clearing and cutting the slope , andtakes the load increasing counter-pressure at the foot of a platform slope of 2 397 m. The total clearingvolume is 115. 23 x 10' m’, and the total back pressure rock volume is 6 881. 16 m’. Through the reason-able construction design guiding the engineering practice, the mine eliminated the hidden danger and achieved good results.
