ShAI-8 PORTABLE IN-MINE ELECTROMAGNETIC PULSE ANALYZER
ShAI-8 is designed for operational prediction of gas-dynamic phenomena in the course of outburst prone formations development.
SHAI-8 allows solving the following tasks:
- detecting the rock mass structural failure zones, where the accumulation or redistribution of stresses is actively occurring; at that, the intensity of electromagnetic emission is significantly higher than in materials with decompressed stresses;
- detecting the increased rock and gas pressure zones associated with increased gas-dynamic activity in coal seams.
The scope of SHAI-8 application is not limited to a set of tasks related to the safety and efficiency of mining operations in coal mines in Ukraine, and can be expanded with field studies on assessing the stress&strain state of any rock masses.
