Description
Technical field：
The invention belongs to permeability variation Detection Techniques field, it is related to before and after a kind of seam mining unconsolidated formation in overlying strata stratum
By the permeability variation detection process under mining influence, particularly a kind of shallow overburden Seam Mining unconsolidated formation infiltration rate measure of the change
Method.
Background technology：
Chinese coal economic situation continued downturn, coal of the current coal price already below certain areas since 2012
Charcoal production cost, particularly traditional coal bases-North China type coalfield, North China type coalfield is deeper due to working seam, and coal exists
The unsafe factor run into production process is more, for example water damage, Gas Disaster, top board disaster etc..The Northwest is due to coal seam
The geological conditions of preservation is relatively simple, coal mining advantage of lower cost, the unsafe factor being related in progress of coal mining
Degree of danger is relatively low, therefore northwest has turned into the topmost base of the coal in China energy.Due to northwest coalfield Energy Base
Coal seam be mainly Datong seam group, buried depth is shallower, and the subject matter that coal seam is related in recovery process is Quaternary aquifer
Water damage prevent and treat problem, Quaternary aquifer protection problem.Therein 4th is that loose aquifer water damage has turned into threat coal seam
The main of exploitation prevents and treats water problems, and the water protection mining of arid area has turned into the weight of the Northwest's ecological environmental protection it
Weight.
At present, two problems of aspect are related generally to for the preventing and treating of unconsolidated formation water damage, one be Atmospheric precipitation infiltration,
Its as aquifer water supply problem；Another is that Quaternary Strata is stablized by deformation, motion and again after seam mining
Permeability situation of change afterwards.Both of which is related to foregoing anti-harness the river and water protection mining problem.For Atmospheric precipitation
Research is infiltrated, can be to the critical parameter of estimated offer of inflow rate of mine water, while Quaternary aquifer can also be obtained
Hydrogeological parameter, to Quaternary aquifer watery evaluate etc.；For the water protection mining problem of Quaternary aquifer, lead to
It is the infiltrative change of loose aquifer to cross continuous probe the 4th, and whether the water isolating for being used to evaluate water barrier in unconsolidated formation has
There is self-regeneration function, or show whether Seam Mining is influenceed to this layer of position with result of detection.Therefore it is infiltrative to unconsolidated formation
Change detection is very important, and detection achievement is also significantly.
The current infiltrative research report that yet there are no for loose aquifer, particularly in shallow overburden seam mining mistake
The permeability detection aspect of overlying strata loose aquifer there are no corresponding research contents in journey.Therefore in the urgent need to a kind of wound of exploitation
New property shallow overburden Seam Mining unconsolidated formation infiltration rate variation measuring method, it is loose aqueous to shallow overburden coal seam mining area the 4th to be used to
The permeability change detection and research work of layer.
The content of the invention：
It is an object of the invention to the shortcoming for overcoming prior art to exist, seek design and a kind of shallow overburden Seam Mining is provided
Unconsolidated formation infiltration rate variation measuring method, be used to be to shallow overburden coal seam mining area the 4th loose aquifer permeability change detection
And research work.
To achieve these goals, the present invention first places shallow overburden Seam Mining unconsolidated formation infiltration rate measure of the change device
