Abstract (en)
The invention pertains to a method A method for predictingcrumps and methane hazard. A method for predictingcrumps and methane hazard characterized in that, when using a continuous monitoring system in sections of powered roof supports installed on exploited walls, pressure values are recorded in the elements of the powered roof support and, in real time, based on known changes in the value of pressure, the occurrence and location of crumps of the rock mass and methane hazard are anticipated.
