岩溶陷落柱作为一种特殊地质体,在华北型煤田中广泛发育和分布。华北型煤田岩溶陷落柱发育分布于井田浅部,具有不均匀性,对煤矿安全的危胁较大,研究分析其发育规律对煤矿安全有重要的理论及现实意义。
As a special geological body, karst collapse column widely develops and distributes in North China coalfield. The karst collapse columns in North China coalfield are distributed in the shallow part of minefield, which is inhomogeneous and threatens the safety of coal mines. It is of great theoretical and practical significance to study and analyze the law of their development on coal mine safety.
