Problems solved by technology

These methods are simple and easy to operate, but these monitoring methods can only evaluate the degree of deformation of the roof rock mass after the macroscopic deformation of the roof rock mass occurs, resulting in operators being unable to maintain the roof rock mass in time and increasing the probability of roof fall accidents

Abstract

The disclosure relates to the technical field of mining, and provides a mining device, a roof rock mass monitoring device and a roof rock mass monitoring method. The roof rock mass monitoring device comprises a plurality of monitoring electrodes, a resistivity detection device and a control device. And the plurality of monitoring electrodes are arranged in the roof rock mass. The resistivity detection device is connected with the multiple monitoring electrodes and used for detecting the resistivity of the part, located between any two monitoring electrodes, of the roof rock mass. And the control device is connected with the resistivity detection device and is used for determining physical and mechanical parameters of the roof rock mass according to the resistivity. The probability of rooffall accidents can be reduced.

Description

technical field [0001] The present disclosure relates to the technical field of mining, and in particular to a mining device, a roof rock mass monitoring device, and a roof rock mass monitoring method. Background technique [0002] As the most common accident in the coal mining process, roadway roof fall poses a serious threat to the life safety of underground personnel and the safe production of coal mines. [0003] With the continuous development of coal mining technology, from the traditional coal pillar mining method to the gob-side roadway mining method, as well as the self-formed roadway mining technology without coal pillars developed in recent years, the maintenance of the roadway roof rock mass has always been a key issue in coal mines. The top priority of safe production, and real-time grasp of the deformation of the roof rock mass is the key to timely maintenance of the roof. The traditional methods for roof rock mass monitoring include roadway surface displaceme...
