Determination of working resistance based on movement type of the first subordinate key stratum in a fully mechanized face with large mining height

Abstract The increase in extraction height will increase the mining‐induced overlying strata failure height. In this scenario, the strata pressure behavior is strong in a fully mechanized face with large mining height (FMFLMH), which frequently causes coal wall falls, roof falls, and hydraulic suppo...
