Determination of coal pillar sizes in preparation of seams with paired mine workings

The results of introduction at coal mines of the methods for determination of coal pillar sizes in preparation of rockburst-hazardous seams with paired workings are discussed in the paper. Safe values of advancing in drivage of development workings with formation of yielding have been established.

Efficient assessment of stress state of coal seams liable to rock bursts

The article deals with the method for effective evaluation of stress state and rock burst hazard of sections of coal seams by the predicted output of drilling fines. The suggested engineer solution, i.e. the program modulus «Prediction» allows to represent the formation of the support pressure zone in the marginal part of the seam (or in a mine working) and to control the potential pattern of rock burst hazard manifestation in a mine working under various geological and mining conditions.
