Experimental Research on Performance of New Gas Drainage Borehole Sealing Material with High Fluidity
To ensure the sealing effect of gas extraction borehole in underground coal mine and improve the concentration of gas extraction, a kind of high-flow sealing material which can be injected into the microcracks around borehole was developed. The ultrafine cement as the base material, with water-reduc...
