ABSTRACT
In this article, method increasing the effectiveness of advance degassing described. Laboratory simulation research`s hydroimpulsive impacts on coal seam using equivalent materials are given. Technological schemes to create hydroimpulsive exposure suggested. Theoretical crack growth parameters in the coal seam are presented.

Keywords: degassing, coal seams, hydrodynamic impact, methane.
