大面宽回采工作面无线电波坑透技术
Radio Wave Penetration Technology for Detecting Large Wide Working Face
摘要
Abstract
The penetration distance of the traditional penetration detection system can not fully meet the requirements of the work to solve the problem of coal mining face width increasing gradually and complex geological structure.In order to find out all kinds of geological factors that influence the exploitation of working face and provide accurate geophysical data,based on the theory of radio wave perspective,on the premise of ensuring the data interpretation effect and construction safety,by increasing the transmit power,changing the size of receiving antenna and reducing transmitting frequency,optiinizing the large wide coal face penetration detection technology,and the actual detection of near 300 m wide mining face is carried out in Shanxi Huozhou Coal and Electricity Group.Detection results show that the hidden structure in the working face can be detected quickly and efficiently by adopting the method of low frequency transmission and small coil receiving.This detection process can provide the target area for coal face drilling.关键词
