Background
As is known, for a roadway suffering from rock burst, because the original stress balance is broken, a new balance point needs to be found for stress, at this time, because the external stress (energy) is far larger than the limit stress state of surrounding rocks, a large stress difference exists between deep rock masses and shallow surrounding rocks of the roadway, deep rock mass stress has a tendency of pressing and finally tending to balance towards the shallow surrounding rocks, which is particularly shown in that the roadway has obvious mine pressure, and the roadway shrinks and deforms along with the throwing of a large amount of coal (mine) and rock fragments, so that strain energy is released until the roadway collapses and the stress tends to balance, the rock burst is a dynamic disaster phenomenon occurring in a coal rock mass stratum, and is a result of rapid fracture of rock coal bodies under the comprehensive actions of internal and external physical mechanical changes and stress, and is a typical irreversible energy dissipation process. In these power processes, the energy obtained from the outside of the coal-rock mass and stored energy during formation can be released and dissipated in various forms, such as elastic energy, kinetic energy, expansion energy of compressed gas, thermal energy, and the like. The great destructiveness of the impact mine pressure is that a large amount of energy is released instantaneously from the coal rock mass;
the method mainly comprises the following steps of taking measures for treating the impact mine pressure from two aspects of strategic defense and active danger relief, wherein the strategic defense mainly comprises a mining release layer, selecting a proper mining sequence, a mining method and a coal mining process when mining design is carried out, mining a coal bed without impact danger firstly, striving to eliminate factors forming the impact mine pressure, and the active danger relief measures for impacting the mine pressure mainly comprise methods such as pressure relief blasting, coal bed water injection, drilling pressure relief, directional crack method and the like;
the pressure-relief blasting method can release elastic energy accumulated in the coal body to the maximum extent, and a pressure-relief damage area is formed near the coal slope, so that a pressure rise area is transferred to the deep part of the coal body; the reasonable arrangement and the reasonable charging amount of the vibration blasting not only form rock mass vibration, but also form a loosening zone of the coal body to a certain extent, and the coal falling is convenient; the detonation wave (stress wave) formed by explosive explosion is superposed with the pressure formed by mining, and exceeds the limit state, so that the pressure of a rock body is relieved or the pressure of an impact mine is triggered, and researches show that: the electromagnetic radiation is the result that heterogeneous materials such as coal bodies and the like deform and break under the loading condition, and is formed by the variable speed movement of charged particles formed in the charge migration and crack expansion processes caused by the non-uniform variable speed deformation of each part of the coal bodies, experiments show that when various coal-rock concrete rheological fractures, broadband electromagnetic radiation is generated, is sensitive to an acoustic emission signal and has a Kaiser memory effect, the electromagnetic radiation signal can reflect the degree and the speed of the coal-rock body fracture, the main recording indexes comprise the intensity amplitude and the pulse frequency of the electromagnetic radiation signal, and within 30 minutes after pressure relief blasting, if the pulse number of the electromagnetic radiation changes violently, the deformation and the fracture in the coal wall are violent in the period, the impact mine pressure is likely to occur, so that the pressure relief process of the pressure relief blasting mode for the impact mine pressure has great danger, and the danger signal existing in the pressure relief process of the pressure relief mode for the pressure relief for the impact mine pressure cannot be performed by the prior art Effective monitoring, effective evaluation and effective treatment;
for this reason, we have made extensive studies to propose a rock burst monitoring system based on pressure relief blasting.
