摘 要:高产高效矿井主要指在矿产资源比较丰富情况下,运用先进工艺以及机械设备,同时运用科学开采方案对矿井展开开采工作。在社会不断发展进步过程中,在能源建设以及能源发展方面国家提出了全新要求。煤炭行业属于传统性行业,对于国家经济发展做出的贡献比较大。但是其在发展过程中产生的耗能比较大,会出现产能浪费问题,并且安全事故经常发生,因此高产高效矿井的有效建设十分必要。High-yield and high-efficiency mines mainly refer to the use of advanced technology and mechanical equipment,and the use of scientific mining schemes to carry out mining work in the case of relatively rich mineral resources.In the process of continuous development and progress of society,the country has put forward new requirements in terms of energy construction and energy development.The coal industry is a traditional industry and has made a relatively large contribution to the country's economic development.However,the energy consumption generated in the development process is relatively large,the problem of capacity waste will occur,and safety accidents often occur,so the effective construction of high-yield and high-efficiency mines is very necessary.
