Problems solved by technology

Due to the difficulty in grasping the law of mine pressure, unreasonable setting of hydraulic support resistance often occurs: a) when the roof is not in contact with the hydraulic support, there will be an empty roof; b) when the roof is in contact with the hydraulic support, the uneven force will cause pressure frame, causing damage to the hydraulic support and threatening the safety of underground operators

Abstract

The invention relates to the field of stope mine pressure control, in particular to a detection device and method beneficial to improving the interaction relation between stope overlying strata and a hydraulic support. The detection device designed by the invention is provided with the probe and the laser range finder, so that the distance between the hydraulic support and the top plate of the device can be measured, when the top plate descends and the probe is stressed, the pressure borne by the probe can be measured through the spring dynamometer, and a top plate hollow form cloud picture and a hydraulic support stress cloud picture are generated through matrix calculation; workers can conveniently adjust the posture of the hydraulic support in time, the interaction relation between the hydraulic support and overlying strata of a stope is improved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of mine pressure control in a stope, in particular to a detection device and a method which are beneficial to improving the interaction relationship between the overlying rock in the stope and the hydraulic support. Background technique [0002] The most important thing in the coal mining industry is safe production. In the complex and changeable underground, the problem of roof safety is becoming more and more prominent. In fully mechanized mining face mining, it is very important to manage the roof of the working face. If the roof of the working face is not well managed, it is easy to induce some coal mine safety accidents. Hydraulic support is one of the important equipment for roof management. [0003] When the hydraulic support is used for coal mining, it is in the process of forming a support system for the overlying rock formation "coal wall-support-goaf has fallen gangue". Relatively speaking, the coal wall ...
