摘　　要：针对某煤矿典型深部矿井的特点,对E3202工作面的顶板进行了分类,分析了E3202工作面开采过程中的周期来压和动压系数变化规律,最终确定了E3202工作面的来压特点,得到了推进度与周期来压的线性公式,并据此对E3202工作面的支架参数的合理性进行了分析,分析结果表明:所用支架完全满足E3202综放工作面的支护要求,可为类似条件的工作面支护设计提供技术参数。Aiming at the characteristic of a typical deep coal mine,the roof of E3202 working face is classified,the laws of periodic weighing and dynamic pressure coefficient（dpc） changes at E3202 working face are studied.Linear formula between advance degree and periodic weighting is achieved by determining the pressure characteristics of E3202 working face;according to this,the rationality of support parameters at E3202 working face are analyzed.The results show that the supports fully meet the supporting requirements of E3202 caving face,which can provide technical parameters for face supporting design with similar conditions.
