Abstract

The invention relates to a deep well outburst simulation experiment method and a rigidity regulation and control device and belongs to the technical field of coal and gas outburst simulation experiments. The method comprises steps of determining rigidity of a theoretical loading system of an outburst simulation experiment and designing a rigidity regulation and control device according to rigidityof the theoretical loading system and rigidity of an actual loading system; rigidity of the actual loading system is regulated and controlled through the rigidity regulation and control device to beconsistent with rigidity of the theoretical loading system, and distribution of the force loaded on a coal body by the actual loading system is regulated and controlled to be consistent with mining-induced stress distribution of a deep well coal seam roof through the rigidity regulation and control device. The method is advantaged in that by arranging the rigidity regulation and control device, the simulation test loading boundary is consistent with the actual engineering boundary, and accuracy of the test result is improved.

Description

technical field [0001] The invention belongs to the technical field of coal and gas outburst simulation experiments, and relates to a deep well outburst simulation experiment method and a stiffness control device. Background technique [0002] Laboratory physical simulation experiment is an important research method to study the mechanism of coal-rock gas dynamic disasters. Scholars from various countries have carried out a series of outburst simulation experiments by developing coal and gas outburst simulation test devices with different characteristics, and obtained the influence of stress, gas pressure, adsorption, etc. on outburst disasters and their intensity. In recent years, in order to further study the protrusion mechanism and obtain quantitative research results, large-scale three-dimensional similar simulation test devices have been developed. [0003] The existing similar simulation test devices provide support for the development of prominent simulation experim...
