所有的研究表明,在地下采矿工程影响下地表的移动和变形取决于覆岩的强度。但是由于这一问题的复杂性,到目前为止尚无公认的结论。这也与深入地研究岩体强度影响移动和变形分布曲线形状和形式的数值参数有关。现仅对充分开采水平或缓倾斜单一煤层条件下的问题进行讨论。已经获得的论点,提供了用影响移动过程特点的确定因素计算岩体强度的可能。水平移动(倾斜)的分布是地表移动的基本微分方程,这一点是明确的。充分开采水平煤层条件下水平移动无因次曲线的
All studies show that surface movement and deformation under the influence of underground mining projects depend on the strength of the overburden. However, due to the complexity of the issue, no conclusive conclusion has been reached so far. This is also related to the in-depth study of the numerical parameters that influence the shape and form of the rock mass on the movement and deformation distribution curve. Only the issue of fully exploiting horizontal or gently inclined single seams is discussed. The arguments already obtained provide the possibility of calculating the strength of the rock mass with certain factors that influence the characteristics of the moving process. It is clear that the horizontal shift (tilt) distribution is the basic differential equation of surface movement. Full exploitation of horizontal coal seam without horizontal movement under the condition of no
