Abstract

The invention discloses a multi-stage blockage double-end observation method. The observation system used includes a detection system, a blockage system and a supply propulsion system. The detection system includes a first detection unit, a second detection unit, a third detection unit and The fourth detection unit is provided with a slot joint between adjacent detection units, and each detection unit includes a connecting pipe and a leaking pipe arranged in parallel, and the connecting pipe and the leaking pipe of the adjacent detecting unit pass through the slot joint Connection, wherein the communication pipes of adjacent detection units are kept in communication, the leakage pipes in the first detection unit and the second detection unit, the third detection unit and the fourth detection unit are in communication, and the leakage pipes in the second detection unit and the third detection unit are connected. The leakage pipe between them is divided into two independent parts by the card slot joint, which are the detection section I and the detection section II. The observation method of the invention can inject water into two detection sections at the same time, increases the measurement terminals and improves the measurement efficiency.

Description

technical field [0001] The invention belongs to the technical field of measuring the damage range of rock mass on the roof and floor of mines, and in particular relates to a multi-segment plugging and double-end observation method. 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 formula is ...
