Choice of design decisions on development of fields taking into account results of geodynamic division into districts and geometrizations of dangerous zones

Article preview

Data on use of information on block structure, geodynamic and geomechanical condition of the massif of rocks are given in article at design of development of layers of coal fields. It is recommended to carry out geodynamic division into districts and to consider results of researches in the course of design of mountain works at different stages of development of a field with allocation of three large-scale levels.

Particular formation of higher rock pressure zones with intensive mining of contiguous seams at coal mines of the «Suek-Kuzbass» CO

Article preview

The problem of mining the suites of contiguous coal seams is considered. The sequential manner of seams mining essentially has influence on change of rock and gas pressure. The results of calculation and construction of borders of zones of higher rock pressure are presented. The analysis of conditions of hazardous zones formation is given.

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

Article preview

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.
