Abstract

Because of China's coal mine gas disaster is serious, for a single outburst low permeability coal seam,pre-drilling gas drainage by cross-seam holes is the main means  to solving the gas disaster . Aiming at the problem of the coal roadway strip and the working face outburst removal, the experimental study on cross-seam holes pre-drilling gas drainage in floor roadway. The evolution law of gas pressure along with the extraction time is analyzed, the key parameters of the best extraction efficiency are obtained. The experiment was carried out in the test mine, The research shows that cross-seam holes pre-drilling gas drainage in floor roadway effectively solve the outburst problems without protective layer mining and single coal seam, and achieved remarkable results, the coal roadway safety belt tunneling and mining face, which plays an important role.
