Mine Debris Flow Control Technology And Research Of The Project Cost

Slope safety affects the normal production of mine directly, small slope Angle influences economic benefit, so how to control the slope safety is one of the main problems in coal mining process. Combining with the actual engineering, this paper studies the boundary of open pit slope stability, the plan within the dump and optimization in slope bottom, control measures of the debris flow, the main research results are as follows:(1) Application limit equilibrium method, slope critical sliding field theory to evaluate the stability of the boundary slope and determine the stability condition of the slope and its dangerous area.(2) To the boundary slope make use of numerical simulation analysis, reveals the rock stress distribution characteristics and evolution, determine dangerous area and the size of deformation, provide the basis to the.(3) Design scheme for the advance slope reinforcement measures, the slope Angle were taken10°,11°,12°,13°and critical state Angle, application sliding surface technology and limit equilibrium method, evaluate the stability of the five different schemes and choose Angle for13.2°control scheme after optimization.(4) In the south area, long time continuous and short time strength rainfall are security threats to the slope of dump, precipitation could cause landslides and debris flow, set flood ditch in upper and set drainage pipe of the dark in two sides, prevent landslides induced dump debris, make sure the deeper safety.
