Current status and prospects of intrinsically safe electromagnetic wave drilling systems
The external interference in drilling is small,and conducting geophysical exploration in drilling can greatly simpli-fy the forward inversion interpretation model of geophysical exploration,which is the direction of future development of un-derground geophysical exploration technology in coal mines.Wireless electromagnetic wave measurement-while-drilling tech-nology is used to transmit the data measured during drilling to the hole mouth.Data can be transmitted thanks to the technol-ogy without requiring the use of specialized communication lines in the hole,effectively solving the technical problem of the"last mile"transmission of coal mine drilling exploration signals.We introduce the composition of the wireless electromag-netic wave while-drilling-measurement system and the current technological development status of each part,list the existing problems in the technical equipment,and focus on analyzing the accuracy,type,stability and power range of the measure-ment short joints in the wireless electromagnetic wave system.Finally,the types and technological development trends of fu-ture measurement short joints,high-speed data transmission,and multidisciplinary collaborative digitization are prospected.It is proposed that wireless electromagnetic wave measurement while drilling and data transmission systems are important com-ponents for achieving full process,intelligent underground exploration operations,transparent coal mine geology,and intelli-gent drilling detection.
