Abstract

The invention discloses a multi-stage blocking double-end observation system, which includes a detection system, a blocking system and a supply propulsion system, and the detection system includes a first detection unit, a second detection unit, a third detection unit and a fourth detection unit, Slot joints are provided between adjacent detection units, and each detection unit includes communication pipes and leaking pipes arranged in parallel, and the communication pipes and leakage pipes of adjacent detection units are connected through the slot joints, wherein the corresponding The connecting pipes of the adjacent detection units are kept connected, the leakage pipes located between the first detection unit and the second detection unit, the third detection unit and the fourth detection unit are kept connected, and the leakage pipes located between the second detection unit and the third detection unit are connected. It is divided into two independent parts by the card slot joint, which are the detection section I and the detection section II. The observation system of the invention can inject water into two detection sections at the same time, thereby increasing the measurement terminals and improving the measurement efficiency.

Description

technical field [0001] The invention belongs to the technical field of determination of the rock mass failure range of the roof and floor of mines, and particularly relates to a multi-stage plugging double-end observation system. Background technique [0002] The measurement of the failure range of the roof and floor of the mine is an important parameter to mark the occurrence state of coal and rock. It is a key basic parameter in the study of mine water prevention and control. Therefore, it is necessary to master the rock movement law and determine the damage range of the roof and floor rock to study the formation of the water channel in the mining surrounding rock. Usually, numerical simulation, empirical formula prediction, field measurement and other means are used. However, due to the complex field conditions, to a certain extent, the numerical simulation cannot reflect the field situation well, and the empirical formula is expected to be blinded. [0003] First of al...
