Based on the two supports crushing accidents during the process of mining in Wulanmulun Coal Mine,the paper predicted the reasonable support resistance for fully mechanized mining face by mine pressure observation and the stability analysis of thick and hard roof structure.The research ensured safety and efficiency production in31403 mining face and can provide the basis for support selection of fully mechanized mining face under similar conditions in Shendong mining area.%针对乌兰木伦煤矿3-1煤四盘区开采中的两起压架事故,通过31402工作面后续开采阶段的矿压实测,结合厚硬顶板破断块体结构的稳定性分析,对后续综采面支架合理工作阻力进行了预计。保障了31403工作面安全高效生产,为神东矿区类似条件下综采面的支架选型提供依据。
