Application of Comprehensive Detection Technology in Detecting Collapse Columns in Coal Mining Face
In order to accurately grasp the distribution position of collapse columns in the 1301 fully mechanized mining face and provide detailed geological data for subsequent production of the mining face,combined with the on-site situation,it is proposed to first use radio perspective technology to conduct full coverage detection within the mining range of the mining face,use slot wave exploration technology to detect the identified abnormal areas in detail,and finally verify the position of collapse columns determined by drilling and carry out grouting reinforcement and sealing.A detailed analysis was conducted on the layout plan and detection results of geophysical and drilling technologies.The results showed that the adopted detection methods can achieve precise positioning of the collapsed columns in the mining face.The comprehensive geophysical and drilling results are close,and the mining face can adopt targeted measures such as advance reinforcement and grouting based on the detection results to reduce the impact of collapsed columns on the mining face,creating good conditions for efficient coal mining.
