In this paper, through the description of the oil emulsification failure analysis and treatment results of the hydraulic system of the Atlas COP1838HD+ rock drill equipped with TBM, the arrangement and working conditions of this type of rock drill on the TBM equipment are different from those of

Based on the analysis of the application of cantilever TBM and self-propelled inverted arch trestle in Daqing project, this paper discusses the standardized configuration of new-type machinery for highway tunnel construction. The application of the cantilever roadheader and the self-propelled

The original mining equipment in our mine is relatively backward, the workers are labor-intensive, the driving efficiency is low, and the safety cannot be well guaranteed. For this reason, high-efficiency trackless mining equipment such as new hydraulic rock drilling rigs has been introduced

The rock is hard in Dunde Mining Company，and the manual drilling is labor-intensive，the drilling efficiency low and the underground working environment poor． To ensure mine production capacity，and improve drilling efficiency and underground working environment，Dunde Mining Company has introduced

Under the background that domestic mines are gradually shifting to deep ore body mining，in the face of the complex environment of“High ground stress，high ground temperature，high karst water pressure and strong mining disturbance” in deep well mining，this paper proposes a mining method of open field

At present, the quota for mechanized supporting construction of railway tunnels is under refinement while corporate construction technology management and cost control are under exploration. In the paper, with the example of excavation, concrete spraying and other sub-measurement of mechanized
