Engineering Test of Gas Ablation Agent in Mine Gas Control

Abstract

Gas is a major threat to the safety of coal mine production, Gas Ablation Agent is a major component of methane oxidation bacteria, added a special catalyst, used to eliminate the high concentration of gas biological solvents, gas reduction speed, low cost, non-toxic harmless characteristics. Gas Ablation Agent can quickly decompose or convert gas into other harmless substances, eliminate or reduce gas in coal seams, reduce gas pressure and gas content, so as to eliminate the prominent risk of coal and gas, is a new biochemical technology to control coal mine gas. After 24 hours, the gas content decreased by an average of 3.64m3/t and 2.24m3/t respectively. Gas ablation microorganisms, while breaking down methane, can promote the rapid decomposition of methane adsorbed in coal bodies. Compared with the conventional excavation method, the number of construction drilling holes decreased by about 92%, the total number of digging days decreased by 59 days, and the efficiency of coal extraction increased by 3.2 times. Gas Ablation Agent is an effective and environmentally friendly technical method to control gas, which is of great practical significance for the prevention and control of coal and gas, and the promotion of efficient and safe production.
