A Study of Project Experiment and Optimization Concerning Gas Control of Fully Mechanized Caving Face in Extremely Thick Coal Seam
According to the problem of gas in Tashan Coal Mine 8104 fully mechanized coal face, fully mechanized coal face gas emission composition and characteristics was analysed, gas control plan of fully mechanized coal face was studyed in extremely thick coal seam.Two typical kinds of scheme; the U type ventilation face gas management scheme and U + I type ventilation face gas management scheme. The second scheme has set up closed special drainage roadway, except fly ash plugging and moving wine - shade.Gas concentration was controlled in 0.3% ~ 0. 7% in upper corner on working face, Gas concentration was controlled under 0.4% .Finally, gas controlling scheme in U +1 type ventilation face has been selected.
thick coal seam fully mechanized coal face gas gushed out drainage management plan
