摘　　要：在用薄板理论分析白腊坪煤矿K1 3煤层顶板的应力分布规律的基础上 ,根据最大拉应力强度理论建立顶板初次及周期来压步距的计算式 ,利用该计算式在现场实施顶板来压预报结果表明 ,用薄板理论研究薄煤层坚硬顶板的应力分布规律是合理的。In the paper,the stress distribution of the roof has been studied by use of the thin plate theory,and on the basis of maximum stress theory,the formulas for first roof pressure and periodic roof pressure have been derived. During the field test,the writers have succeeded in prediction pressure in use of the formulas.
