单体支柱工作面高初撑力控顶效果的研究

Research on Roof Control Result of High Setting Load in Single Prop Face

根据现场实测资料的统计，分析了单体支柱工作面支柱初撑力不足的主要原因，提出了提高初撑力的措施，同时论述了高初撑力对顶板的控顶效果，指出初撑力的提高可大大改善工作面的安全生产状况。

The cause of insufficient setting load of single prop face was analysed according to the statistics of practically measured data in the field and the ways to raise setting load was proposed. It was pointed that increased setting,load can greatly improve safe production condition at single prop faces based on the description of roof control result by high setting load.
