Gas parameter characteristic and region prediction in Erdaoling coal mine area

摘要

In accordance with the large amount of test data, a systematic study of the coal body structure and gas parameter characteristic of Erdaoling coal mine area is carried out. With single index method, gas content method and comprehensive index method, region predictions of coal and gas outbursts are conducted in major coal seams of the mine, which offers reference and guidance in improving the efficiency and pertinence of preventing gas outbursts.
