Product Introduction

The YZG9.6 mine-used seismic monitoring trajectory instrument while drilling is developed based on two invention patents: "A Borehole Depth Detection System Based on Elastic Waves" and "A Mine In-drilling Inclination Exploration System and Its Measurement Method". It consists of a host and a probe (equipped with a three-component sensor). Using the drill bit as a power source, this device can obtain the dynamic wave field and energy spectrum of the entire drilling construction process through data collection and processing. It can objectively and automatically invert lithology and structures. It also records behaviors during the drilling process, such as the starting time of drilling, the interval of rod measurement, the number of drill rod replacements, the effective rock - breaking time of drilling, the idle running time, and the retraction of the drill rod. These records can serve as an objective basis for borehole acceptance, prevent fraud in drilling operations, and improve drilling efficiency.

 This instrument has won the title of "New Product in Anhui Province". It has high - precision trajectory measurement and good stability. It is suitable for trajectory measurement of water exploration boreholes, geological exploration boreholes, gas pressure measurement boreholes, and gas drainage cross - layer and in - layer boreholes in underground coal mines. It can also be used to determine the lithology exposed by boreholes and measure the final hole depth for acceptance of the above - mentioned boreholes, realizing unattended borehole acceptance and providing technical support for transparent geology in coal mines.

Main Features

1．Intelligent and Portable Host: It is intelligent and easy to operate, capable of directly generating graphs on - site and displaying two - dimensional inclination measurement data.

2.Multifunctional Host: It has functions such as geological logging, geological surveying, and can be used as an explosion - proof camera and an intelligent terminal.

3.High Precision: The inclination accuracy is ±0.2° and the azimuth accuracy is ±1°.

4.Unique Vibration Acceleration Signal Recording Function: It can analyze effective information such as drilling efficiency and construction time.

5.Easy to Use: It does not require dedicated drilling rigs and cable - passing drill pipes. By equipped with different - sized casings, it can adapt to boreholes of different sizes.

6.Long Working Time: The working time can reach up to 48 hours.

7.Large Storage Space: With 32GB of storage space, it can store a large amount of data.

8.Convenient Equipment: Only the inner core of the probe needs to be replaced without stopping drilling.
