Alex The Nao Slope And Waste Dump Deformation-induced Disaster Mechanism And Safety Dumping Measures

Not only the row of depot security problem relates the mine directly the safety in production, but also involves to the peripheral environment security and nearby inhabitant's safety.However speaking of these row of depot site engineering geology condition difference, its guarantee row of depot security difficulty increases, however expels the platoon depot and the soft batholith base slope security problem which induces relates the mine regular production directly, as well as the peripheral environment and the inhabitant life and property security, at present many mines faced with such question, this mainly are the detachment condition limit, therefore needs to solve such problem, for this present paper in view of the soft batholith base bleed depot side slope stability computational method, the security measure as well as the following platoon depot optimized design question has conducted the research, mainly has completed the following research content:①According to the geological investigation newspaper, determined the influence row of depot side slope security stable mechanics parameter, to the mine row of depot mud-rock flow formation condition, forms the mechanism to carry on the simple summary and the analysis.②Applies the grey theory method, carries on the forecast and the analysis to the large-scale platoon depot and the thick soft crag hillside basis side slope complex distortion trend of development, has analyzed the row of depot distortion characteristic and the trend of development; Has carried on the row of depot displacement quantity and the rainfall amount relevant analysis, and summarizes its change characteristic, in order to for prevents the mud-rock flow to occur with the safe protection provides the policy-making basis.③Using the side slope critical slipping field theory method determination side slope sliding surface position, then uses the limit zero-method to carry on the computation to the side slope rock mass stability.④The application value simulation method has conducted the research to a row of depot to the side slope destruction mechanism, had determined the deformation range and the warning area, for prevented the stair collapses slippery or forms the mud-rock flow disaster to provide the basis.⑤Has carried on the optimized design according to the slipping field theory counter-analysis method to a row of depot to the side slope, the determination row of depot design proposal.According to the row of depot environment engineering geology condition with the row of depot distributed situation, guarded against Honggou to a row of earth to carry on the design, in order to provided the safeguard safely for the row of depot side slope.⑥Selects the different water ratio and the soil body mixture uses to simulate the drill hole note thick liquid, then carries on in the room the intensity experimental study, selects the best allocated proportion plan, in order to provides the scientific basis for the safe reinforcement.
