摘要

A method of preventing outburst coal seam during conducting in it the preparatory in-seam working by road heading machine includes the pre-drilling of advancing unloading wells (AUV) from the working face of grasses. AUV shall be drilled horizontally and parallel to each other at the bottom of the coal seam from wall to wall output. Then the coal seam, which is above the AUV subjected to vibration. Along with the process of vibration measuring deformation of AUV. The duration of the vibration is determined by the duration deformation process of AUV according to their diameter, which is equal to at least 20% of their original size.
