Abstract
With the rapid development of open-pit mining technology in China, the mining strength of open pit mine is higher and higher, the steps are to promote faster and faster, the resulting work steps collapse is also more and more unsafe factor, working steps in open-pit mine collapse have become a key problem in mine production safety.Especially for some of the original joint fracture of high strength mining in open-pit mine, under the condition of groundwater and frequent construction disturbance, work steps buckling collapse are prone to occur.Taking the open-pit tuff mine of Zhoushan green petrochemical base as an example, this paper analyzes the main factors affecting the collapse of working bench, and studies the measures to prevent the collapse of working bench under the condition of high-intensity mining, which has certain guiding significance for open-pit mining construction of similar mines.
