In order to understand the migration law of respirable dust and gain reasonable design parameters for dust control on a super-long double-shearer fully mechaniz
This paper describes a field and numerical investigation of the overburden strata response to underground longwall mining, focusing on overburden strata movemen
One of the most serious conundrum facing the stope production in underground metalliferous mining is uneven break(UB: unplanned dilution and ore-loss). Although
The study examined joint discontinuity spacing effect on drilling condition and performance in selected rocks in Ilorin and Ibese areas, Nigeria. Five samples f
The development and achievements of modern coal mining with stowing are discussed in this paper. The necessity of developing coal mining with stowing is briefly
The water abundance of mine floor limestone needs to be solved urgently as the average depth of coal mining in China has increased gradually. A method is presen
High ash thermal coal from India was used to conduct the dry processing of fine coal using a pneumatic table to evolve a techno-economically novel technique. Th
New solid backfill mining technology provides unique technical advantages for ‘‘three-under'' coal mining which refers to coal resources trapped under
After gas drainage,the outburst seam is dry and,consequently,during subsequent mechanized mining,unwanted dust production is extensive.Because the hard dustfall
Based on the elastic plate theory, a mechanical model of thin plate for the first caving of overlying roof rock in steep mining face was established. The analyt
