Abstract
The invention discloses a method for detecting the water injection effect of coal mine impact coal bed, which detects the water injection effect of a coal mine impact coal bed through analyzing an electromagnetic radiation image which is generated by coal bed samples in the process of a compressed destructive test. The invention has the advantages of simple and scientific method and accurate test effect, which is not influenced by physical factors, and is particularly suitable for the security detection work of large-scale coal mines.
Description
One, technical field:
The present invention relates to the method for inspection of the mine safety method of inspection, particularly coal mine impact coal seam infusion effect.
Two, background technology:
The rock burst in colliery is because power surpasses the strength degree of coal and rock, accumulates in that the energy in the coal petrography discharges the phenomenon that causes suddenly around the tunnel, and it has brought great threat to mine safety.What generally adopt for the improvement of coal seam rock burst at present, is standing shot and two kinds of methods of coal seam water infusion.Check to these two kinds of methods has drilling cuttings method and rock noise method.These two kinds of methods of inspection are subjected to the influence of physical factors such as coal seam water cut after the water filling bigger, and the effect of check is inaccurate.
Three, summary of the invention:
The objective of the invention is to overcome above-mentioned not enough problem, a kind of method of inspection of coal mine impact coal seam infusion effect is provided, this method utilizes electromagnetic radiation method that coal seam infusion effect is tested, method simple possible and be not subjected to the influence of physical factor, and test effect is accurate.
The technical scheme that the present invention is adopted for achieving the above object is: samples of coal pulled at first, in testing machine, the coal sample of gathering is carried out the fail in compression experiment, measure the ELECTROMAGNETIC RADIATION SIGNATURE of in destructive process, launching then, statistics and the concentrated situation of observing stress, thereby the purpose of realization prediction coal mine impact coal seam infusion effect.
Described wet coal sample and the natural raw coal when samples of coal pulled, need gathered.
The method of inspection of a kind of coal mine impact coal seam infusion effect according to claim 1 is characterized in that: the method for using during the statistics ELECTROMAGNETIC RADIATION SIGNATURE is to utilize the drawing tools bag in the mathematic software to realize.
Characteristics of the present invention: the present invention utilizes and analyze the electromagnetic radiation image that the coal seam produces in the process of fail in compression test, checks coal mine impact coal seam infusion effect.It is accurate that this method has a test effect, the advantage that not influenced by physical factor.
Four, embodiment:
Below in conjunction with embodiment the present invention is described in further detail, but is not limited to specific embodiment.
The concrete implementation step of the method for inspection of this coal mine impact coal seam infusion effect is:
1. samples of coal pulled.Need to gather wet coal sample and natural raw coal.
2. in testing machine, the coal sample of gathering is carried out the fail in compression experiment.
3. measure the ELECTROMAGNETIC RADIATION SIGNATURE of in destructive process, launching, the data that collect are made the tables of data form.
4. call in the Mathematic software package plot order 3 measured data are made the data statistics sheet form.
5. observe the degree of successively decreasing of image, the state if image tapers off, then flood effectiveness is better.
Claims (3)
1, a kind of method of inspection of coal mine impact coal seam infusion effect, it is characterized in that: samples of coal pulled at first, in testing machine, the coal sample of gathering is carried out the fail in compression experiment, measure the ELECTROMAGNETIC RADIATION SIGNATURE of in destructive process, launching then, statistics and the concentrated situation of observing stress, thereby the purpose of realization prediction coal mine impact coal seam infusion effect.
2, the method for inspection of a kind of coal mine impact coal seam infusion effect according to claim 1 is characterized in that: need gather wet coal sample and natural raw coal when samples of coal pulled.
3, the method for inspection of a kind of coal mine impact coal seam infusion effect according to claim 1 is characterized in that: the method for using during the statistics ELECTROMAGNETIC RADIATION SIGNATURE is to utilize the drawing tools bag in the mathematic software to realize.
