METHOD FOR EVALUATION OF OUTBURST HAZARD OF COAL SEAM ZONES

摘要

Usage: The invention relates to mining and more specifically to a safe mining works on coal seams vybro- soopasnym: Summary of the invention: there is provided a hole drilled to a depth greater than the area of ​​effect on production of rock mass, it outside the zone effect generating on coal seam is produced continuously, measurement of an initial gas evolution rate. If the speaker has an upward character, the measurement is performed to obtain r of its maximum value. If the speaker has a downward character, t derivatives recess hole at the next interval value and determining an initial gas evolution rate to obtain its maximum value and on .vybrosoopasnosti judged by comparing the maximum value obtained with a critical value of the initial gas evolution rate. with C
