چکیده انگلیسی
Currently, methane gas disasters in underground coal mines are a major problem which seriously threatens safe mining. This study employed soundless chemical demolition for fracturing coal seams with low permeability. Additionally, the fracturing theory and failure mechanisms of soundless chemical demolition agents were investigated. Materials such as CaO, naphthalene-based water reducer, sodium gluconate and silicate cement were used to prepare the novel soundless chemical demolition agent, whose optimum proportion was discovered to be 90:3:5:7 by carrying out orthogonal experiments. The innovative demolition agent cracked briquettes and the maximum width of cracks reached 16.33Â mm, showing significant potential for improving the permeability of coal seams.
