Seismic exploration work in the coal field has been playing an important role in the economic development. exploration result is directly related to the coal geological exploration results of the investigation and study, the development of coal resources and many other factors. So, in order to improve the exploration speed and economic benefits and ensure the accuracy of the exploration, choosing the suitable exploration instrument and methods become crucial. In Dec, 2011, there is one coalfield seismic exploration in Tao Jia Shan Lingshi, Shanxi Province, China.For looking for high quality and excellent price-performance ratio seismograph, the customer choose France seismograph and our high-precision(32-bit ∑-△ADC) distributed land seismograph (Model: GS101) to make the comparison testing.
Testing Way:
Customer preparing the France seismograph and our high-precision(32-bit ∑-△ADC) distributed land seismograph(Model: GS101), then customer respectively places the geophone in the same point, make the synchronous shooting and make the synchronous acquisition.
Testing Parameters:
| Sampling Rate | 1ms |
| Acquisition Time Length | 1s |
| Channel Space | 10m |
| Channels | 48 |
| Geophone | Two series, two parallel |
| Geophone Type | Natural frequency 10Hz,moving-coil geophone |
| Weather | Sunny |
| Temperature | -4 ~ 4 ° C |
| Testing Method | Induced well shooting |
| Well Depth | 3m |
| Explosive Weight | 1.5 ~ 2 kg |
After the testing, the customer makes get the comparison result. The result is exciting and good. Our seismograph equipment gives customer very good performance and deep impression. Now please check the comparison information.
