Definitions

  • the invention pertains to a method for predictingcrumps and methane hazard.
  • Patent application PL 178986 describes a method of forecasting of rock mass crumps and provoking crumps.
  • the method consists in drilling in a crump-producing area a small-diameter hole with a seismic-acoustic sensor placed at the end. Signals from the sensor are sent to an interpretation system that determines the probability of occurrence of a high-energy shock of the rock mass that initiates a crump. If a hazard is present, signals from the interpretation system blow up the explosive material placed previously in the drilled hole. The explosion provokes a control crump of the rock mass.
  • Patent application PL 165582 describes a method of limitation of roof crumps.
  • the invention is applied when performing mining works in the vicinity of large vertical cracks in the rock mass with delamination at the contact of strata of different susceptibility.
  • the method of limitation of roof crumps consists in drilling at least one hole to the delamination between a brittle rock layer and a solid rock layer and pumping a medium that fills the delamination through the hole.
  • the essence of the invention is the use of changes in pressure that take place in the rock mass before a crump and the use of such changes to anticipate possible occurrence of a crump.
  • the method for predictingcrumps and methane hazard according to the invention is 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.
  • pressure is recorded in individual working actuators, in auxiliary systems, and in control and protection equipment (safety valves, overflow valves, limit valves).
  • control and protection equipment safety valves, overflow valves, limit valves.
