Eagle's Nest Phosphate Rock Slope Stability And Governance

Bongching in open pits are a lot of in our country. Iron mine stone which in our country account for 90% about ore gross. Coloured metal about 50% are from open pits. Mine slop stability and father are very important in oerating pit design, the economy and safety mine, and raiseing an economic performance. If the slope lose stability, the operating pit will be aggravated, the safety of a capacity and personnel are furnished, biggest the earth affect the operating pit of normal safety capacity.By the operating pit the increment of the depth , operating pit slope's safety stability problem is more and more outstanding, How reasonable, carry on the mineral resources development to make use of efficiently and economically, lower the loss of the resources, the safe production that promises the mineral mountain business enterprise is the problem that the mineral resources developer concerns together. So the research of the side ascent stability with manage a problem is open-air mine the mineral mountain side ascent engineering of core problem, it relates to to the mineral mountain directly of normal produce and the safety of the personnel,equipments. With open mine work of carry on, at the side ascent rock body inner part, original of should the dint appearance will along with open to dig of carry on but take place variety, cause should thedint re- distribute with should dint concentration etc. effect, at this kind of new of should the dint appearance under, the side ascent rock body will take place the different form and different scale to transform, even breaking.phosphorite In Yunnan turns the group limited company kunyang sun sharp mountain phosphorite mineral, it is open-air to adopt a field for one open-air adopt a field, the level has already make public of the tallest elevation for 2213 m, make public an elevation with the mountain form toward east,west two sides to lower gradually. Because of various history reason, now become of adopted the top of a side ascent and don't press the relevant design and safety to rule to establish safe platform with clean up terrace, with the result that the side ascent become a from the big inclined plane with 2213～2085 m, its scaleboard make public of the perpendicular height is a 40～120 m, the side ascent Cape 42 ° ～50 ° , average is 46 °. The scaleboard rock strata noodles because the rain water flushes moderate breezes to turn a function, the partial district surface layer rock is already the morals and custom become the mire form, and the agreeable layer shed off, sheding off a layer thick about 20~30 cm, it rains the rock strata integrity better.The side ascent coping bush is exuberant, moved and prognosticate and transform, the ascent crest has no an ambulation to transform an evidence, cutting ditch and lining up theditch intact.This text aims at the sharp mountain phosphorite mineral open-air adopt a problem for appear, use an equilibrium method of extreme limit to carry on the stability calculation analysis and research to the sharp mountain phosphorite mineral side ascent present condition from two angle. The stability degree that passes a research to the sharp mountain phosphorite mineral side ascent contain one understanding that settles, the side ascent evaluation carries on an analytical evaluation according to the stability calculation result of, so the whole side ascent is basically stable. The side ascent that puts forward correspond also defends catchment and prevent from the side ascent feet super dig, the side ascent monitors over a long period of time, the safety management etc. in the production line manage measure to adopt by insuring the sharp mountain phosphorite mineral the area production smoothly progress.
