Description

Technical field [0001] The present invention relates to the field of coal mine gas control, in particular to an automatic control coal mine gas experimental gas distribution device and experimental equipment. Background technique [0002] In recent years, with the improvement of coal mine mechanization and the rapid increase of mining depth, coal seam storage conditions have become increasingly complex, ground stress has gradually increased, and the degree of coal fragmentation has increased, resulting in rapid and large-scale reduction of coal seam permeability. The strengthening of pre-drainage of gas in this coal seam tends to be a theoretical and technical bottleneck, and the situation of coal mine gas governance and safety management is still very severe. Under this situation, we need to update our concepts and seek effective anti-outburst technical measures with simple technology, less investment, and proven safety while ensuring safety. [0003] With the rapid development o...
