Factors that increase the danger of gas dynamic phenomena in coal mines

The diversity of the mining and geological component of coal deposits, their individuality, complex geodynamic conditions of coal seams mining taking into account the high-speed tunneling and mining operations are risk factors that require constant study. Often there are situations that cannot be answered unambiguously, and their resolution requires non-linear approaches. Technical and technological solutions should be aimed at localizing geodynamic risks. The high probability of destabilization of the rock mass due to anthropogenic impact requires timely actions to prevent catastrophic consequences. In such cases, it becomes relevant to identify the forms of risks, use proven and adequate methods to study the reaction of the environment and fix (control) the development of complex natural processes and “atypical” (special) forms of their manifestation. Since 2014, coal enterprises with underground mining have been working in the mode of using a multifunctional safety system — MFSB, which ensures the use of additional means of control, with adaptation tests of new technologies and methods of prediction and prevention of gas dynamic phenomena at coal deposits. The fundamental role in the implementation in practice of geodynamic monitoring in large-scale research plays a formed set of means and methods of control, extremely accurately and effectively replenishing the structure of MFSB of the operating coal mining enterprise.
