| 摘 要： | 针对中小型煤矿安全存在顶板事故多发、形势严峻的突出问题,笔者选择了具有中小型煤矿代表性的平煤新峰四矿的顶板条件做为背景实验模拟了煤层覆岩裂隙演化过程,总结分析了回采工作面裂隙场演化规律,发现了回采工作面裂隙场演化规律和顶板防治之间有着内在的联系.研究结果对中小型煤矿,特别是福建煤矿的顶板事故的防治具有重要的指导意义.

| Abstract: | To deal with the prominent issue of the small and medium sized mines which exit the problem of frequent roof accidents and severe situation, the author chose the Pinmei Xinfeng fourth mine which typically represented the roof condition of the small and medium sized mines, as the experimental model to simulate the evolving process of the cover-rock cracking. Thus, the evolving rules of cracking field of the working face was analyzed and summarized, and the interconnection of the above rules with the roof control was found out. This researching result is significant to the control of roof accidents in small and medium sized mines, in particular, the Fujian mine accidents. |
