The Gas-Geology Law And Gas Forecasting In Sanyuan Minefield

As everyone knows, although the state of the coal mine safety managementattaches great importance to, and put a lot of manpower and material resources, but, as aworldwide problem, coal mine safety situation is still grim. Gas in the coal formingprocess is created and stored in coal and rock in the multicomponent mixed gas of coalmine safety production, is the first killer. Tectonic control of gas generation, migrationand preservation, geological structural complexity in control of coal and gas outburstdanger, therefore the study of gas geology theory on gas prevention and control is veryimportant.Gas distribution plate structure theory from the source analysis of gas occurrenceregularity, and analysis of coal seam from formation to structural changes, this paperanalyzes the previous research theory and experience analysis of the phenomenon, threeyuan of mine tectonic evolution characteristics and gas occurrence regularity. Accordingto the collected three yuan of coal mine gas geological data, analysis of the geologicalstructure, roof and floor lithology, magmatic rock, coal seam thickness and buried depthon gas occurrence influence, find out the main control factors of controlling gasoccurrence. The gas content and buried depth linear relationship, the prediction model isestablished, on the deep coal bed and coal seam mining area into the gas contentprediction. Application of statistical method to mine deep coal mining working face gasemission forecast. Analysis of the impact of coal and gas outburst geological factors,combined with the content of coal seam gas pressure and, on three yuan coal mine coaland gas outburst forecast.
