The Research Of Stope Blasting Parameter In Sublevel Caving Method With Large Space Between

This topic put forward is should the Kingsoft store mine mountain the mining produces it need, research of purpose want to put forward the big spacing structure superior return to adopt to blow up the parameter.Mainly study from the theory for this text, the number simulation and the physics form the simulation experimented three what square face the issues to resolve to launch the concrete research, and these three part verifies each other, complement and perfect, end design a superior blow up the parameter, to guide the spot the production has important realistic meaning. Theoretically, analyzed the subsurface back to adopt the medium fan-shaped and quick-fried bore to blow up the mechanism and big parameter of spacing structures each choice that returns to adopt to blow up the parameter.The exploitation plays the plasticity theory and hurts the mechanics and rocks to split the mechanics element, after considering the beginning to start to hurting and hurt the factor two times, getting the crevice rock body stanchion form medicine sack( the matches to pack under the medicine circumstance) to blow up to break the expression type of sphere.Compute a bore path as the compression semidiameter and crevice semidiameters of the 80 cms according to the mine rock the physics characteristic of the Kingsoft store mine mountain. Pass the theory analysis, adopt to blow up the parameter to the well next time excellent to turned the choice to put forward some new devices, big parameter of spacing structure of in keeping with Kingsoft store mine mountain of end establishment next superior return to adopt to blow up the parameter. The number imitates the aspect, for objective reappear the fan-shaped bore to blow up the wave of stress to spread the whole process, research resist the line and the bore bottoms be apart from of take and be worth sphere, verification the theory is excellent to turn to design the well to adopt the rationality of blow up the parameter next time, making use of large and limited dollar computation the software-ANSYS8.0/ LS-DANY970 software to blew up the function process to carry on the number simulation, and as a result carried on the homologous theory to the output analysis.Imitate the conclusion and theories deduces the result to agree with to match, mutually argument rationality. For recognize under pure and big circumstance of spacing the dissimilarity collapses the mine to tread to be apart from of put the regulation of mine, the assurance is superior to put to collapse to tread to be apart from, this thesis carries on the physics form simulation to put the mine experiment.The experiment as a result expressed the Kingsoft store mine mountain under the big parameter of spacing structure the bottomless stanchion articulated shield collapses to fall the logarithm of timw fitting method logt back to adopt medium, collapse the mine to tread to be apart from to take 3.4 ms as proper, the too small easy formation hangs the summit, carrying the body of department mine too greatly hard let out to thus prove theoretically excellent turn to design to collapse the rationality that the mine treads to be apart from.
