Seismic Exploration of Mined-out Area

Mined-out area is caused by the artificial digging or natural geological movement. Theexistence of mined-out area makes the safety of the mine safety production under a lot of problems. People and equipments are likely to fall into themined-out area and bring damage and loss. Therefore, how to explore underground mined-out area and know the morphological characteristics and condition of goaf caving space etc. become the key technical problems now.

For solve this problem, in Jan, 2015, one of our customers used our high-precision (32-bit ∑-△ADC) distributed land seismograph(Model:GS101) to explore underground mined-out area.
