Bryukhanov P. Justification of parameters of methane drainage borehole sealing as a factor of mining operations safety increase

The object of research - the process of mine safety by the deformable sealing degasification wells. Purpose - to establish the laws of the deformation of degasification wells and justify the parameters of their sealing to improve drainage and safety of underground mining. Research methods: analytical methods for determining the causes of deformation wells and reduce the efficiency of decontamination, computer modeling of processes in the mountain range, the simulation on physical models for quantitative analysis of the deformation of rock mass near the degasification wells, as well as field observations and research in underground workings to confirm the results of analytical studies and formulation of proposals for revisions to industry regulations governing the methods and schemes degassing coal mines. Idea about the mechanisms and patterns of deformation process degasification wells in violation of the continuity of the rock during the excavation of coal, determining the parameters of sealing efficiency of decontamination and mine safety. "Guidelines for the choice of a rational depth sealing degasification wells." Developed "Proposals for adjustment of the SOU 10.1.00174088.001-2004" degassing coal mines. Requirements for methods and circuits degassing ". The expected economic effect of implementing development website was 4,605 million USD.
