在金属矿床地下开采中,气能是凿岩机的主要动力.提高和稳定工作面的压气压力是提高设备工作能力的条件.通过增大空压机的排气量和改造压气管线固然可提高工作面压力,但前者需增加电耗和压气成本,后者难于实施而且代价高。原苏联有色金属矿冶科研所通过对23座有色矿山的调查,研究出一种可合理利用压气能和提高气动凿岩机生产效率的有效技术,即在压气系统中加入蓄能贮气室。文中对贮气室的结构、安装地点的选择、设计、自动控制等做了全面的介绍。
In the underground mining of metal deposits, gas is the main driving force of rock drill. Improve and stabilize the pressure of the face is to improve the working conditions of equipment. By increasing the displacement of the compressor and reforming the gas pipeline, the pressure on the working face can be increased. However, the former needs to increase the power consumption and gas pressure cost, which is difficult to implement and costly. The former Soviet Union Nonferrous Metals Research Institute of Mining and Metallurgy through the survey of 23 non-ferrous mines, developed a reasonable use of compressed air and improve the efficiency of the production of pneumatic rock drilling technology, that is, in the gas storage system to add storage chamber. The article on the gas chamber structure, installation site selection, design, automatic control made a comprehensive introduction.
