| Abstract:Water and gas mixing spewing was encountered in the construction process of coal mine hydrogeology drilling, which is a serious threat to the construction safety. The grouting plugging was tried with failure. 3 sets of device of drilling tool blowout preventer, orifice flexible sealing blowout preventer and flooding closed water-gas separator for integrated control were designed and applied with obvious effects. |
