Arch Math Model of Thick Sand Layer Mining Unload Failure in Shallow Seam

Abstract:

Under the basis of the “arch” failure of thick sand layer in preliminary period in shallow seam through field experiment, arch math model is set up. The conclusion establish the basis to study the coupling problem between key stratum (key block) and the sand layer.
