Results of computer modeling of stress-deformed state of rock massif with the use of software FLAC 5.00 in zones of geological fault influence with amplitude that does not exceed 3 m are presented in the article. According to the results of the modeling, the dependences of vertical stress change in handing wall and foot wall of geological fault with variable fault plane amplitudes and contour well deformation have been obtained. Using the interpolation data method, 3-D grid visualization of vertical stress in space is got. The analysis of modeling results on full movement vectors is also presented. Results of previously conducted analytical calculations are compared with received data. Conclusions regarding the implementation of the offered method are made on the basis of undertaken investigations. The obtained results with sufficient accuracy in practical application can be used to determine the location of underground gas generator wells. Also these investigations will give the opportunity to maintain the necessary exploitation wells crosscut. Besides, it will allow consume coal reserves in the faulting zones in order to obtain power and chemical generator gas, chemicals and heat.
