Propagation characteristics of electromagnetic waves in mine roadways

Journal of Applied Geophysics, 2020
Abstract The environment of an underground roadway following a mine disaster affects multimedia communication during mine rescue. The propagation characteristics of electromagnetic waves in a wireless mesh network were studied by means of theoretical analysis, experiments, and simulations.

Influence of mine shallow roadway on airflow temperature

Arabian Journal of Geosciences, 2019
With the increase of the depth of mining, the working environment of deep well is worse; in order to improve the working environment of deep mine, on the basis of a lot of practice, the idea of adjusting the temperature of the air flow in the mine was put forward.

Characterization of strata behaviour around mine roadways

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1997
A 3 yrs project aimed at developing a safe and economical support system for roadways in the Cayirhan Coal mine was carried out. During the pilot study of the project, a 300-m section of a roadway supported by Split-Set, Yielding super Swellex, Sis Resin, Fosroc Resin bolts, and rigid and yielding steel arches was investigated.

Study on Support Technology of Deep Mine Roadway in Xingdong Coal Mine

Geotechnical and Geological Engineering, 2020
Because of the large depth of the mine, the original use of bolt, mesh and spray composite support, the roadway shrinkage deformation is more serious, which not only affects the use but also endangers the safety of production. According to the deformation of surrounding rock and the characteristics of engineering technology, the following three ...
