Experimental study of enhancing coalbed methane recovery by carbon dioxide injection driving methane
In order to enhance coalbed methane recovery, taking a self-developed largecale simulation system for the platform, a modeling experiment of driving CH4 by CO2 gas injection was studied. The results of experiment indicates that there is a significant lag
Research on inversion high mining pressure distribution and technol-ogy of preventing dynamic disast
Under two rock strata combination conditions, over 10,000 microseismic events were received with microseismic location monitoring technology which possessed by the author\'s studying team, used in fully mechanized coal face of Huafeng Mine of Xinwen Coa
According to the research results of motion parameters of coal-gas flow, ana-lyzed the formation mechanism of shock waves at different states of coal-gas flow in the process of coal and gas outburst, and briefly described the two possible cases of outburs
Numerical simulation and analysis of underground pressure in the 101 fully-mechanized top coal cavin
The forms of roof break,roof fall,and effects of the region scope in a fully me-chanized top-coal caving (FMTC) face of the 101 fully-mechanized top coal caving face of the Tingnan Coalmine were analyzed by UDEC and FLAC software.The analysis result confi
In order to determine how a roadway withstands a momentum wave and de-termine the extent of damage to rock surrounding the roadway under different force wave peak impacts, the roadway dynamic response state was analysed using numerical simula-tion method.
According to the structure and stress trait of bearing bolts,a lateral-vibration mechanics model was established for them,and the relation between lateral-vibration fre-quency and axial load was analyzed; then,lateral-vibration trait of bearing bolts was
The experiment of gas and coal dust explosion propagation in a single laneway was carried out in a large experimental roadway that is nearly the same with actual envi-ronment and geometry conditions. In the experiment, the time when the gas and coal dust
Analysis of nonlinear dynamic character in the surrounding rock system for deep buried underground e
Combining the field monitoring results of a deep-buried tunnel in Chongqing,the dynamic characteristics of the surrounding rock system under high in situ stress was analyzed by phase space reconstruction, calculating correlation dimension, Kolmogorov entr
