摘　　要：根据某煤矿具体的地质和工作面开采技术的具体情况,采用现场实测研究方法,对综放工作面回采期间周期来压、支架工作阻力和煤壁片帮与推进速度的关系进行了现场的实测,得到了在不同推进速度情况下工作面一些矿山压力显现的变化规律,对确定工作面合理推进速度有积极的意义。According to the spot condition of geological and mining technology in an certain coal mine, this paper researchs the relation of mining velocity and strata behaviors, working resistance of supports, falling of the fully-mechanized coal mining by the method of spot observation, and some laws are obtained. These laws have a positive guidance in determining the proper mining velocity.

关 键 词：推进速度 综放工作面 矿压显现
