Abstract

The invention relates to a coal rock recognition method based on a drilling return slag image, and belongs to the field of coal mine drilling. The method comprises the following steps: S1, collectingdrilling return slag, and obtaining a return slag image; s2, preprocessing the image; s3, segmenting the image into a plurality of pixel groups according to the gray features of the coal seam and therock stratum; and S4, calculating the proportion of the coal rock pixel points in the total number of the pixels, and identifying the coal rock stratum type. Compared with the prior art, dependence onartificial experience is reduced in the using process, the judgment standard is unified, and the recognition precision is improved.

Description

technical field [0001] The invention belongs to the field of coal mine drilling, and relates to a method for identifying coal rocks based on images of slag returned from drilling holes. Background technique [0002] Drilling construction is the most fundamental technical measure for disaster management such as gas, water prevention and fire prevention in underground coal mines. The lithology identification of the existing drilling construction is mainly performed manually by drilling rig operators based on the slag returned from the drilling. The identification method is rough and the identification accuracy is low. [0003] The existing coal rock identification methods in coal mines are mainly based on the shearer's sense of touch, image features of coal rocks, radar waves and other parameters. At present, this technology is mainly applied to coal shearers in unmanned working faces, and has no application in the drilling process. Contents of the invention [0004] In vi...
