Electrical Tomography Exploration of Sliding-Hazardous Pitwall Rock Masses

摘要

The authors anlyze conditions and factors that influence coal pitwall stability, and substantiate applicability of electrical tomography for pitwall exploration. Experimental studies of physico-mechanical properties of Bikinsky brown-coal pitwall rock mass are reported. The article proposes a procedure for the electrical tomography exploration of weak layers and lentils within geological column.
