| 摘 要： | 通过对实验结果的分析，得出了煤样水分含量与其坚固性系数之间的关系；同时得出潮湿煤样干燥后的坚固性系数低于原始干燥煤样的坚固性系数；还得出了同一煤样的坚固性系数随撞击次数的增加而增大，并据此提出了最佳撞击次数的确定方法。

| Abstract: | Obtained the following results by the experiment and research the parameters relation between the water content and protodyakonov coefficient of coal sample as well as the parameters of dried coal sample are lower than original dried coal;showed the protodyakonov coefficient are increasing as that of strikes frequency.On these grounds,the best method strike frequency is given. |
