The rock burst monitoring method has a plurality of methods, and the drilling cutting method is used as a simple and reliable rock burst monitoring means, has important roles in rock burst prediction, pressure relief effect inspection and the like, and is valued by engineering technicians. The construction of the intelligent mine is an important direction of development of each mine, but the drilling cuttings method is used as a main means for rock burst monitoring, the traditional modes of manual drilling cuttings, weighing and recording are continued all the time, and the requirement of intelligent development of the mine is not met.
Drilling cutting method: a method for identifying the impact danger by constructing drilling holes in a coal seam according to the amount of coal dust discharged per meter, the change rule of the coal dust and the related dynamic phenomenon in the drilling process.
The principle of the drilling cutting method is to determine the corresponding coal stress state by measuring the amount of coal dust in the drilling hole. If the drilling of the coal seam is regarded as the digging of a micro roadway in the impact dangerous area, the coal seam drilling process is just like the rock burst simulation test with reduced scale.
The critical indexes of the drilling cutting method generally comprise drilling cutting quantity indexes, drilling cutting granularity indexes, dynamic phenomena and the like, and all the critical indexes of the drilling cutting method reflect the peak value and the concentration degree of the stress of the coal body. In areas with high impact risk, multiple indexes are often simultaneously generated, so comprehensive analysis and judgment are needed.
The traditional construction method comprises the following steps:
