Mine rock mining damage area integrated detecting device and method

Abstract

The invention discloses a mine rock mining damage area integrated detecting device and method and relates to the technical field of mine floor rock damage area detection. The mine rock mining damage area integrated detecting device comprises a plugging system, a guide system, a leakage detecting system and a propelling and feeding system, wherein the leakage detecting system comprises a connectingpipe and a transfer switch; as one of the major improvements, the transfer switch comprises a cylindrical cavity, inside which a base, a sliding valve and a spring are arranged, the base is providedwith a water guide hole II and a water guide hole III, the sliding valve is provided with a water guide hole I, the sliding valve can freely slide inside the cylindrical cavity, and the water guide hole I can form two independent water guide channels respectively with the water guide hole II and the water guide hole III. The mine rock mining damage area integrated detecting device can be water-supplied by a single external operating system and reduce the number of external systems, reduce the number of pipes inside a drill hole to one, thereby solving the problem of twining of multiple pipes inside the drill hole due to excessive external systems. The mine rock mining damage area integrated detecting device can improve the measurement efficiency and the accuracy of measurement results.

Description

technical field [0001] The invention relates to the technical field of measuring the damage range of mine floor rock mass, in particular to an integrated detection device and a detection method for the mining damage range of mine rock mass. Background technique [0002] The measurement of the damage range of rock mass on the roof and floor of mine is an important parameter to indicate the occurrence state of coal rock. It is a key basic parameter in the study of mine water prevention and control. Therefore, to study the formation of water-conducting channels in mining surrounding rocks, it is necessary to grasp the movement rules of rock strata and determine the damage range of roof and floor rock mass. Numerical simulation, empirical formula prediction, field measurement and other methods are usually used. However, due to the complex site conditions, to a certain extent, the numerical simulation cannot reflect the site conditions well, and the blindness of the empirical fo...

AI Technical Summary

Problems solved by technology

However, due to the complex site conditions, to a certain extent, the numerical simulation cannot reflect the site conditions well, and the blindness of the empirical formula is relatively large. As the mining depth increases, the applicability of the empirical formula becomes worse and worse.

[0003] The technical deficiencies in the existing research reports on this aspect of the prior art are as follows: First, due to the excessive number of pipelines working at the same time in the existing observation equipment, especially during the propulsion process, the problem of pipeline entanglement in the borehole is prone to occur Secondly, the existing observation equipment generally requires two sets of detection pipelines, which are respectively pushed upwards, and there is a problem of fixing the inner and outer detection pipelines; finally, the traditional swelling capsules need to be filled with water separately, which is cumbersome and difficult to work. The amount is large, and the existing technology fails to solve the above three problems at the same time
