本文叙述在掘进分段平巷时采用T2GH型装运机代替电耙的效率对比、成本分析和经济效果,并以此为例介绍了对新设备、新工艺的评价方法。 Mattagami Lake锌矿位于魁北克州的西北部,距Amos城以北大约180公里,与该城有公路相通,并有铁路与Senneterre-Ghibougamau国营铁路接轨。矿床简介及开拓方法1957年用物探法发现这一矿床。1963年9月产量规模为3000吨~*/日,1964年底达4000吨/日。现在开采的1号矿体是该矿今后十年的主要开采对象,210米水平以上的硫化矿储量约为2000万吨。另一较小的2号矿体正在
This paper describes the efficiency comparison, cost analysis and economic effect of using T2GH type loader instead of electric rake when driving the sub-level roadway. And this paper introduces the evaluation method of new equipment and new technology. The Mattagami Lake, located in the northwestern part of Quebec, about 180 kilometers north of Amos, is connected to the city by road and has a rail link with the Senneterre-Ghibougamau State Railway. Mineral Deposit Profile and Exploration Methods The discovery of this deposit by geophysical prospecting in 1957. September 1963 production scale of 3,000 tons to * / day, by the end of 1964 up to 4,000 tons / day. The No. 1 orebody now being mined is the main mining target of the mine in the next ten years. The reserves of sulfide ore above 210 meters are about 20 million tons. Another smaller No. 2 ore body is in progress
