Abstract

The invention discloses a multi-section plugging double-end observation system, comprising a detection system, a plugging system and a supply propelling system, wherein the detection system comprises a first detection unit, a second detection unit, a third detection unit and a fourth detection unit; a slot joint is arranged between adjacent detection units; each detection unit comprises a communicating pipe and a water leaking pipe arranged in parallel, the communicating pipes and the water leaking pipes of adjacent detection units are connected by the slot joints, wherein communicating pipes of adjacent detection units keep communicating; the water leaking pipes located between the first detection unit and the second detection unit and the water leaking pipes located between the third detection unit and the fourth detection unit keep communicating; and the water leaking pipes located between the second detection unit and the third detection unit are divided into two independent parts by the slot joints, which are respectively a detection section I and a detection section II. The observation system can inject water to two detection sections simultaneously, so that measuring terminals can be increased, and measuring efficiency can be improved.

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...
