Abstract

The invention relates to a gridding type rock mass stress and vibration monitoring device based on a pipe seam type anchor rod, an auxiliary mounting device and a mounting and using method, and the monitoring device comprises a pipe seam type anchor rod body, a strain and vibration sensor integrated grating, a silica gel jacket, a fixed tray, an information intelligent integrated device, and a wired transmission unit. The strain and vibration sensor integrated grating is composed of a plurality of high-precision strain sensors and two vibration sensors, and the strain and vibration sensor integrated grating can be installed in the pipe seam type anchor rod through the special auxiliary mounting device. According to the invention, the micro strain of the rock mass can be sensed more accurately and widely by adopting gridding type multi-point monitoring, the accuracy of the whole monitoring equipment is increased, and meanwhile, a gridding model for monitoring the drill hole is established based on the obtained multi-point strain data, so that the micro deformation of the rock mass can be visually observed, and the working condition of the strain sensor at each point can be judged, the visualization degree of monitoring data is greatly increased.

Description

technical field

[0001] The invention belongs to the field of mine safety monitoring, and relates to a grid-type rock mass stress and vibration monitoring device based on a pipe-slit bolt, an auxiliary installation device and an installation and use method. Background technique

[0002] Mineral resources have always played an important role in the development of the national economy. However, in the mining process of mineral resources, due to the inability to grasp the stress state inside the rock strata in a timely and accurate manner, mine disasters and accidents caused by the appearance of ground pressure emerge in endlessly, especially accidents such as rock bursts and mine earthquakes, which have caused serious damage to enterprises. Huge loss of personnel and property, especially in recent years, with the depletion of shallow mineral resources, deep mining and marine resource mining have gradually become the norm, and the phenomenon of ground pressure will be more serio...
