Lanjian Iron Ore Open Pit Slope Broken With Controlled Blasting Technology Research

With the developmellt of the blasting tecboques, the conbolledblasting, eg. the pre-sPldrig blasting, the smooth blasting, arewidely used in such areas as mine, wate conservancy and roadconedoll, Which makes good profitS and pushes the nationaleconomy forWard. But there are shll some areas where the blastinresults are not so satisfactory mostly because the raration of thegeologic sihatons, the cOIisAnchon tools and blasting eqmpment andIIlatrials. Therfore, the most effective mpach Which assure thegood resuits of the cwilled blasting are adjusting the blastillgparameters and imPoving the blasting methods through the spotteSts and theoritcal analyses, hence achieving the design pmpose.In ths aticle, it is cdried out tha the research of the fragmentationzone controlled blasting of Pangang GrouP the ComPany LanjianMine, the effect of exPloshes with dmerell pdriance on thehighwill, the OPindZation of nehole parameters and steInIninglengh, and the research of charging quantity chargin consAnctionand deonaing pattffo, etc. hereby hoding out the aPProPriatecforlled blasting methOd, parametors apd teclmology fOr thewtedation zone highWall slope blasting. The research result has beenapPlied to Lanian Mine and proved to be approPriate which keePs thehighWll comPlete and hable.
