Embodiment Construction

[0030] Such as figure 1 The shown a kind of subsection water injection observation system in the fissure zone of coal seam goaf comprises a probe 1, an inflation control system 2 and a water injection control system 3, and the probe 1 (such as figure 2 shown), comprising two inflatable capsules 11, a water injection pipe 13 installed between the two inflatable capsules 11 through a connection block 12, an air pipeline 6 and a water pipeline 5, and the probe 1 is installed in the borehole 4, and the inflatable capsule 11 is in close contact with the inner wall of the borehole 4 after being inflated, so as to realize good sealing of both ends of the water injection pipe 13 between the inflatable capsules 11, so that the water flowing out from the water injection pipe 13 will not flow along the borehole 4 The direction of flowing out, said water injection pipe 13 is provided with a plurality of water injection holes 131 (such as image 3 shown), the water in the water injection...

Abstract

The invention discloses an exploring tube used for observing coal seam goaf fissure zone subsection water injection, comprising two aeration capsules and a water injection pipe which is arranged between the two aeration capsules through a connecting piece; the water injection pipe is provided with a plurality of water injection holes; the exploring tube is provided with a gas delivering pipeline and the water delivering pipeline; water inlet holes are arranged on the part of the water injection pipe on the water delivering pipeline; and aeration holes are formed on the part of the aeration capsule on the gas delivering pipeline. The exploring tube of the invention has high water injection efficiency, can inject water rapidly, has good practicality, simple structure, convenient use and low production cost, and is beneficial for promotion.

Description

technical field [0001] The invention relates to a probe, in particular to a probe for segmental water injection observation in a fissure zone of a coal seam goaf. Background technique [0002] The traditional observation method for the fissure zone in the goaf of the coal seam is the simple hydrological observation method of the ground borehole, which needs to be located on the ground within a certain range on both sides of the air return roadway or machine roadway in the goaf, and the main construction data is on the side of the goaf. For each borehole, the height and distribution of the fissure zone in the goaf can be determined through the change of the consumption of borehole flushing fluid during the drilling process. Construction drilling has a great impact on the ecological environment, and the accuracy of observation is difficult to control. In order to increase the height of observation, save the amount of drilling engineering, and protect the ecological environmen...
