| Abstract: | Aiming at especially coal and gas outbursts of Daping Coal Mine of Zhengzhou Coal Group, studies principle of high pressure abrasive jet device and cutting creams for prevention coal and gas outbursts. High pressure abrasive jet cutting creams technology is carried on scene experiment in Daping Coal Mine. This research and experiment show that using the technology can avoid coal and gas outbursts accident, improve tunnel velocity, so its wide application will produce certainly benefit for society and economy. |
