Abstract:
A research into geomechanical processes in a fluid-saturated rock mass is described in the article using the example of undermining a methane drainage borehole located at the industrial site of a mine. Based on the detailed analysis of the mining operations impact, the calculations of radial loads on the borehole casing, of the ground surface displacements and deformations, and as well of the vertical deformations along the methane drainage borehole axis have been carried out. The possibility of performing second mining operations on a protection pillar to minimize the negative consequences of undermining at the maximum coal extraction is considered.
Keywords:
borehole undermining, methane drainage borehole, displacement, deformations, protection pillar, second mining operations, stability, undermining factor, borehole faulting
