[Abstract] 
Key Conclusions:
fiogf49gjkf0d
Harmonious mining in thick coal seam is feasible under the dam. The safety of the earth-rock dam after mining was ensured and the coal resources recovery ratio was improved.
Key Findings:
fiogf49gjkf0d
the top caving harmonious mining technology in thick coal seam beneath the earth-rock dam was put forward and studied.
Objective of the Paper:
fiogf49gjkf0d
To raise the coal resources recovery ratio and protect the earth-rock dam.
Problem Statement:
