Research on the Coupling Effects Between Stereo Gas Extraction and Coal Spontaneous Combustion
In order to investigate the effects of the stereo gas extraction and overlying strata fracture development on the coal spontaneous combustion, through the research of air leakage channel and coal oxidative dynamic, we applied the U+Ⅱ type fully machined workface of Shigang mine to study on the coupling between the stereo gas extraction and overlying strata fracture development, which caused air leakage and spontaneous combustion. The results show that the stereo gas extraction and overlying strata fracture development support air leakage passage and dynamic oxidation to coal spontaneous combustion in goaf and aggravated the process of coal spontaneous combustion. The study provides a new notion of controlling coal spontaneous combustion in the high gas and easily spontaneous combustion coal-seam of fully machined workface, which is of a certain theoretical and practical significance.
