Purpose Hazard management in coal mines is a critical pathway to ensuring the safe production of enterprises. Existing research primarily focuses on adjusting incentive mechanisms and enhancing punitive measures encourage employees engage hazard identification, while comparative studies factors driving these behaviors their moderating effects remain limited. Therefore, this study integrates theory planned behavior (TPB) stimulus-organism-response (SOR) model, introducing working conditions...
Coalbed methane (CBM), as an associated resource of coal, has important strategic energy significance. However, most reservoirs in China have low permeability, which poses challenges for CBM mining. Based on the background acidification to increase production, macroscopic mechanics seepage, mesoscopic morphology observation, and microscopic pore measurement experiments coal under acid treatment were carried out, influence macro-meso-micro characteristics insights into enhancing revealed. It...
Coal bed methane drainage is the main approach to lower risks of coal seam while raising efficiency in natural resource utilization. The negative pressure used for extraction mines largely determined empirically due a lack experimental research on how permeability changes under combined influence effective stress and pressure. This results low gas concentration. In this paper, study effect law complex during co-mining, test system was specially designed determine flow samples different paths...
<title>Abstract</title> Coal, as a complex gas-bearing medium, exhibits unique rheological behavior under mining disturbance. However, with increasing depth, the creep and seepage mechanisms of low permeability coal remain unclear. Therefore, to investigate coupled relationship between gas in coal, time-dependent triaxial experiments were conducted this study. To consider effects gas, modified model based on Nishihara was developed validated by numerical simulations experimental results. The...
Pore fluid chemistry can affect coal hydro-mechanical properties thus influencing gas extraction performance in seam fields and mines. To improve the understanding of this effect, we conducted an experimental study using a self-developed small-angle X-ray scattering (SAXS) micro-loading system in-situ synchrotron SAXS device to investigate nanopore structure changes samples treated with acid alkali solutions followed by loading. The results showed that between these two differ significantly....
