| 摘 要： | 通过三维相似模拟试验研究了底板－煤－顶板组成的力学条件，得出的结论是水采采场上覆岩层的垮落特征及参数与同类条件下的旱采有着显著区别，顶板初次垮落及周期垮落的形状分别为三角形板结构和平行四边形板结构；垮落线与煤层走向是一定角度。

| Abstract: | The completed mechanics system of coal floor and roof has been presented with experiment of three-dimensional simulation in which mining simulation is new and original,The caving characteristics and parameter of overburden around hydraulic jet coal mining face is obtianed which are obviously different from that of other mining method in the same condition. Roof shapes in first and periodic caving are individually triangle and parailelogram plate structure. There is a certain angle between caving line and coal seam strike. |
