试谈茫崖石棉矿开采工艺的改进
The Improvement of the Mining Technology of Mangya Asbestos Mine
【摘要】 矿山开采条件差尤其是地处恶劣条件的矿山改造是如何进行强化开采,根据国内露天开采几十年的经验,陡邦开采作为一种强化矿床露天开采的开采方法,从五十年代初在加拿大出现以来,已得到各国采矿界的普遍重视,该开采方法具有许多优点,是现代露天开采的发展趋势。 自七十年代初以来,先后有不少矿山采用了这种开采方法,使露天矿基建工程量和露天矿初期剥采比大大降低,因而大大缩短了矿山基建时间,对降低矿山基本建设投资和降低矿石成本具有重要意义
【Abstract】 The improvement of the mine techuolagy of the mines which the operating condition is special poor is to use intensive operation One of these methods is called high-slope·operation Which has heen developed from Canada since 1950’s.It is a essential and important method of our nation’s opencut industry.Special attention has been paid by the mines a-11 over the World This method is treated as a Way of modern opencut i-ndustry For it has many advantagesMany a mine has put this method in its mine operation and has gained great benefit from it like declaration of primary stripping ration the shorten of the capital construction period and lower of capital expense etc.This article describes the usage of this method in Mangya asbestos mine And the calculation method of final slope angles and Workig angle are set.So do the design of operating technology.
【Key words】 high-slope-operation; final slope angle; Working slope angle; substage operation; extreme hillside extended hillside;
