Influence law and control mechanism of coal seam permeability on coal and gas outburst

open access: yesMeitan xuebao
Coal and gas outburst is a destructive gas dynamic disaster in coal mines, which seriously threatens the safety of coal mine production. Coal permeability is an important parameter that comprehensively reflects the characteristics of coal seams. The coal

Study on influence of gas content of coal and gas outburst

open access: yesIOP Conference Series: Materials Science and Engineering, 2017
In order to study the influence of gas content on the strength of coal and gas outburst, a set of device for simulating coal and gas outburst is improved by adding flowmeter and gas pressure sensors. The simulation experiments of coal and gas outburst were carried out with gas content of 7.5m3/t, 8.0m3/t, 8.5m3/t and 9.0m3/t respectively.

Multi-physical field parameter response in the whole process of coal and gas outburst under deep high stress

open access: yesMeikuang Anquan
Based on the thermo-fluid-solid coupling law of coal and gas outburst in deep mining, a numerical model of coal and gas outburst is established, and the response of multi-physical parameters in the whole process of coal and gas outburst under high stress

Evolution process and instability mechanism of coal and gas outburst induced by rock cross-cut coal uncovering

open access: yesMeitan kexue jishu
Coal and gas outburst (referred to as outburst) is a complex dynamic disaster phenomenon in the process of coal mining, which seriously threatens the safety production of mines, and the average intensity of coal outburst induced by rock cross-cut coal ...
