Abstract EN
Compound hard roof overlying coal face is the common disaster factor leading to strong strata behaviors.
To solve the long-standing problems of only considering partial factors and large deviation from the actuality when identifying compound hard roof, a mechanical model of compound hard roof based on elastic mechanics is built, from which the stress field distribution equations of compound hard roof are formed and the judging criteria of compound hard roof have been set up.
In this essay, 8101 Working Face of Tashan Coal Mine in China is the research object for criteria and analysis of compound hard roof, and the result is testified by similar model tests.
The research results have provided a basis for judging and dealing with compound hard roof.
