Description
Technical field:
The invention belongs to drilling technique field, relate to a kind of single power source dual pathways country rock mining induced fissure detection system, logical
Cross wall-rock crack development characteristics after detection of coal seam exploitation, research production process coal seam, colliery wall-rock crack development characteristics and evolution machine
Reason problem.
Background technology:
At present, although colliery is at China's energy-consuming accounting continuous decrease, but space of top prominence does not shake, coal
The safety problem that resource exploitation relates to remains the Important Problems of China's energy industry safety monitor.Coal seam in recovery process,
Owing to losing the supporting role in coal seam, goaf overlying top board, underlie base plate and coal body around all can be at the works of mine pressure
With lower generation unstability, rupture, mobile, be finally reached weight new steady s tate.And the crack that surrounding rock failure is grown, then it is underground current
There is the artificial passage of migration in body, such as, in South China, roof and floor water flowing fractured zone will result in overlying strata and floor strata
Strong water content is directly entered adopts space；In the Taiyuan Forma-tion coal seam recovery process of North China, base plate water flowing fractured zone is great
Decrease 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 recent and all to account for the whole nation future the first, owing to Jurassic System Coalfield layer position, northwest is new, it is shallow to bury, coal seam
The water producing fractures that exploitation causes makes Quaternary aquifer water miss, and thus results in the problem such as ecology, groundwater environment.To sum up institute
Stating, adopt wall-rock crack, particularly water producing fractures is grown is to a series of focuses such as Water Inrush, roof water-inrush, water protection minings
The Research foundation of problem, and the detection to water flowing fractured zone, then be the emphasis in engineering practice problem and difficult point.
