摘　　要：通过对东风煤矿43002工作面地质条件以及开采技术条件进行分析,首先确定了工作面顶板压力为321.1kPa,依次计算了倾斜薄煤层合理的工作面支护参数。根据这些支护参数,对43002工作面进行了控顶设计。并在井下布置监测线,进行了支护质量监测,记录监测结果,得出初撑力与顶底板移近量、末前排阻力、冒落高度之间的关系。Based on analyzing 43002 face geological conditions and the mining engineering factors in Dongfeng Coal Mine,first it is determined that the face roof pressure is 321.1kPa,then the reasonable inclined thin seam support parameters are calculated.According to these parameters,the design of 43002 face roof under control is carried out.In underground layout,the monitoring line monitoring support quality and recording monitoring results,come to the relationship multibetween setting load,roof and floor nearer the quantity,end front-row resistance and falling height.
