| Abstract: | Aiming at the problems of high cost, low efficiency, and high safety risk in the mining of extremely broken ore body, a technical scheme of mechanical mining of cantilever roadheader instead of traditional blasting mining was proposed, and the technical scheme was tested in industry. During the test, the mining efficiency, production capacity, technical index and economic index of the cantilever roadheader were tested and analyzed in detail. The experimental results showed that this technology can effectively solve the production problems in the mining of extremely broken ore body, and provide effective solutions and technical support for the future deep resources. The research results have important practical value and significance. |
