摘要
分析了自重应力场和构造应力场中应力随深度的变化规律。给出了由少量硬岩层实测地应力值的结果估算煤层及软岩层地应力值的方法；并结合实例，说明了这一方法的可行性。
The variation law of geostresses with depth in gravitational stress field and tectonic stress field is analyzed. A method is put forward to estimate the Seostress values in coal and soft rock, based on the in-situ measured results of geostresses in hard rock. Some application cases show that this method is feasible.
