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 characteristics of a typical deep mine in a coal mine, the roof of E3202 working face was classified. The periodic pressure and dynamic pressure coefficient of E3202 working face were analyzed. The pressure characteristic of E3202 working face was finally obtained. The linearity formula of propulsion and periodic pressure was put forward. Based on this, the rationality of bracket parameters of E3202 working face was analyzed. The analysis results showed that the bracket used fully met the support requirements of E3202 fully mechanized face, Face support design to provide technical parameters.
