The mined-out area is caused by the artificial digging or natural geological movement. The existence of mined-out area makes the safety of the mine safety production under a lot of problems. People and equipment are likely to fall into the mined-out area and bring damage and loss. Therefore, how to explore the 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 the underground mined-out area.
Delineating ore zone of mined-out area distribution and provides information about geological hazard degree, offer the basis for government decision-making.
