METHOD FOR PREVENTION OF GAS-DYNAMICAL EFFECTS

摘要

A method for prevention of gas-dynamical effects includes drilling wells with installation of release electrodes to the whole depths of those. Well drilling is carried out before fixation of working to connection of roofing and the face at each cut by whole length of the working normally to its axis. The wells are equipped with metal beams with magnetic vinyl at the end, those are connected to each other with electric wire connected to the mine earth loop for removal of static voltage. The distance between the wells and drilling depth are chosen depending on mining-geological conditions and the measure of outburst danger of the section that is developed.
