Abstract：In this paper, study was carried out on two processing methods of direct machine cutting and blasting machine cutting which are to be used in order to solve the blocking problem of the thick and hard rock strata in the process of mining. The movement and stress of the overlying rock strata and the surface settlement caused by the two mothods were simulated in the case of the gob with different compaction rate. The simulated results showed that using the prior parameters for the blasting machine cutting method made the movement of the overlying rock strata larger, but when the direct machine cutting method was used, the movement of the overlying rock strata was smaller. The simulated results obtained by modifying the blasting parameters indicated that the rock movement was smaller, so it conforms to the screening condition.
