Application field
The YDA Huarui YCS60-F Mining Explosion proof and Intrinsic Safety Transient Electromagnetic Instrument Transmitter can only be used in conjunction with the YCS200 (A) Mining Intrinsic Safety Transient Electromagnetic Instrument or TEMHZ75 (A) Mining Intrinsic Safety Transient Electromagnetic Instrument. It has the characteristics of strong emission current, is not shielded by high resistance layers, and can overcome the influence of low resistance cover layers.
This product isYCS 200(A) The intrinsically safe transient electromagnetic instrument for mining or TEMHZ75 (A) is a supporting instrument for intrinsically safe transient electromagnetic instrument for mining, which is used for detecting water rich abnormal areas inside the front of coal mine excavation face.
Main Features
The effective advanced detection distance of the YDA Huarui YCS60-F mining transient electromagnetic instrument (ultra light explosion-proof and intrinsic safety type) is ≥ 200m,Effective detection distance of working face400mCan meet the highest energy efficiency requirements for underground use.
Dedicated mining high-power transmitter: Dida HuaruiYCS60-FMining transient electromagnetic transmitter (explosion-proof certificate number:SHExC13.1050）， As an upgraded version of TEMJF50 mining transient electromagnetic instrument (explosion-proof and intrinsic safety type), it has reduced weight by 70%, halved volume, more compact structure, lightweight system configuration, and is suitable for underground transportation.
The secondary field can be enhanced by increasing the transmission power, improving the signal-to-noise ratio and thus increasing the exploration depth; By repeatedly measuring and superimposing the secondary field through multiple pulse excitations and applying spatial domain multiple coverage techniques, the signal-to-noise ratio can be improved and applied to the complex and noisy underground coal mine roof, floor, and advanced detection.

Application Case 1: Transient Electromagnetic Method Advanced Detection Case
In December 2014, the transient electromagnetic method was used to conduct a geophysical advanced exploration case on Lane 5201 of a certain mine in Tongmei (15 meters before 22:00). The geophysical results showed that there was a significant low resistance anomaly on the left side of the roadway from 0 ° -45 ° direction (the excavation direction was positive) at a depth of 20-180 meters. It is speculated that this low resistance anomaly area is likely a reflection of the water accumulation anomaly in the 8206 goaf of the roadway. It is recommended that the mining party further drill and verify the low resistance anomaly area to avoid accidental water accidents;
Interpretation results of transient electromagnetic advance exploration in the roadway
Verification situation: After communicating with the mining party for the first time, the later drilling results showed that the geophysical exploration results were abnormal and had already been mined8206The water accumulation and drainage areas in the goaf of the working face are consistent, and the comprehensive electrical analysis of the abnormal area in the front right is a symmetrical electrical response of the rich water in the left side.
Application Case 2: Application of High Power Mining Transient Electromagnetic Instrument in Mine Advanced Detection
Excavate along the roadway and arrange 3 survey lines (30 degrees upward for the roof, 30 degrees downward for the bedding, and 30 degrees downward for the floor). By moving the transmitting and receiving coils at the excavation head, 3 advanced detection profiles are formed to identify the possible water rich situation in the goaf ahead of the roadway
▲ Figure: There are a total of three low resistance abnormal areas in the cross-sectional view, with relatively large areas. It is inferred that these areas are enriched with old goaf water after mining. The high resistance part of the yellow strip in the middle should be caused by the safety coal pillars reserved during the mechanical mining process. After comparison by the mining party, the situation is true and highly consistent with the geophysical results.
