Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with specific embodiments, but not limited to specific examples.

[0009] The specific implementation steps of the inspection method for the impact coal seam water injection effect of this coal mine are:

[0010] 1. Collect coal samples. Wet coal samples and natural raw coal need to be collected.

[0011] 2. Conduct compression destructive experiments on the collected coal samples in the testing machine.

[0012] 3. Measure the electromagnetic radiation signal emitted during the destruction process, and make the collected data into a data table form.

[0013] 4. Call the plot command in the Mathematic software package to make the data measured in 3 into a statistical table form.

[0014] 5. Observe the degree of decline of the image. If the image is in a state of decline, the effect of water injection is better.

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

1. Technical field: [0001] The invention relates to a coal mine safety testing method, in particular to a testing method for the impact coal seam water injection effect of the coal mine. 2. Background technology: [0002] Rockburst in coal mines is a phenomenon caused by the sudden release of energy accumulated in the coal rocks around the roadway when the power exceeds the strength limit of the coal rock mass, which poses a great threat to mine safety. At present, two methods of loosening blasting and coal seam water injection are commonly used to control coal seam rock burst. The tests for these two methods include the cuttings method and the ground sound method. These two inspection methods are greatly affected by physical factors such as the water content of the coal seam after water injection, and the inspection results are not accurate. 3. Contents of the invention: [0003] The purpose of the present invention is to overcome the above-mentioned problems and provid...
