一、前言我国小型矿山很多,特别是有色金属矿山。这些矿山的地理位置偏僻,交通不便,开采年限較短,多数用柴油发电,动力不足,成本高。所以,它們的机械化程度低,多半用手工开采,占用劳动力多,劳动强度大,工效低,急需应用一些动力消耗少、效率高、基建投資少而建成速度快的机械来对这些矿山进行技术改造。此外,在地质勘探、筑路及其他部門,也存在类似情况。适应这一需要,1959年初,我們开始了电动凿岩机的研究工作。1960年7月,对机构的主要参数进行了修改,試制出长沙60型电动凿岩机,并进行了工业試驗。1961年6月初步鑑定結果认为:結构形式好,效率高,操作平稳和噪音小。
I. Introduction Many small mines in our country, especially non-ferrous metal mines. The remote location of these mines, inconvenient transportation, mining life is shorter, the majority of diesel power generation, lack of motivation, high cost. As a result, they are less mechanized, mostly hand-mined, labor-intensive, labor-intensive and inefficient, and urgently need to be retrofitted to these mines with machinery that requires less power consumption, high efficiency, less capital investment, and faster construction . In addition, there are similar situations in geological exploration, road construction and other sectors. To meet this need, in early 1959, we started the research of electric rock drill. July 1960, the main parameters of the organization were modified, trial production of Changsha 60 electric rock drill, and conducted an industrial test. June 1961 initial appraisal results that: a good structure, high efficiency, smooth operation and noise.
