| titleOfInvention | A kind of method of surface mine hole bottom leakage preventing structure and Anti-seeping technology |
| abstract | The invention discloses the method for a kind of surface mine hole bottom leakage preventing structure and Anti-seeping technology, belong to mining technique field.A kind of surface mine hole bottom leakage preventing structure of the present invention, at open-air pit bottom up, spreads underlayer, geomembrane, upper bed course and protective layer successively.The method of Anti-seeping technology, step includes the processing of processing → protective layer of processing → upper bed course of processing → geomembrane of the processing → underlayer at open-air pit bottom.The present invention realizes low cost and solves the problems, such as that surface mine cheats bottom leakage, and good seepage-proof property, when effectively prevent strip mining transformation and closing behind hole to the Mining of lower orebody at open-air pit bottom, surface water can crush crack along superficial part and enter subsurface rock, underground is poured in the rimala of original construction, underground gushing water amount is increased, increases the effluent cost of underground, it is also possible to the problem of flooding well accident of generation when serious. |
