Description
Technical field：
The invention belongs to drilling technique field, is related to a kind of single power source binary channels country rock mining induced fissure detection system, leads to
Wall-rock crack development characteristics after detection of coal seam is exploited are crossed, study colliery production process coal seam wall-rock crack development characteristics and evolution machine
Reason problem.
Background technology：
At present, although colliery is continued to decline in China's energy-consuming accounting, space of top prominence does not shake, coal
The safety problem that resource exploitation is related to remains the Important Problems of China's energy industry safety monitor.Coal seam in recovery process,
Due to losing the supporting role in coal seam, goaf overlying top plate, underlie bottom plate and surrounding coal body can be in the work of mine pressure
With lower generation unstability, rupture, movement, weight new steady s tate is finally reached.And the crack of surrounding rock failure development, then it is underground current
The artificial passage that body is migrated, such as will be caused in overlying strata and floor strata in South China, roof and floor water flowing fractured zone
Strong water content, which is directly entered, adopts space；In the Taiyuan Forma-tion coal seam recovery process of North China, bottom plate water flowing fractured zone is great
Reduce the thickness of effective water barrier, cause Water Inrush to take place frequently；The Northwest progressively becomes the weight of coal resources in China exploitation
Point region, coal production capacity is the first in the recent and following whole nation that accounts for, since northwest Jurassic System Coalfield layer position is new, buries shallow, coal seam
Water producing fractures caused by exploitation cause Quaternary aquifer water miss, thus cause ecology, groundwater environment the problems such as.To sum up institute
State, adopt wall-rock crack, particularly water producing fractures development is to a series of hot spots such as Water Inrush, roof water-inrush, water protection mining
The Research foundation of problem, and to the detection of water flowing fractured zone, then it is the emphasis and difficult point in engineering practice problem.
