华北型煤田岩溶陷落柱综合探测和分布规律特征

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。本文阐述了华北型煤田内岩溶陷落柱形成的基本条件及其分布规律,研究并总结了已揭露的岩溶陷落柱的形态、分布、含水和导水性特征,对其成因和类型的划分进行了探计。

Karstic Collapse Column Integrated Detection and Distribution in North China Type Coalfields

The karstic collapse column is a kind of special geological bodyand it is widely developed and distributed in North China type coalfields. Karstic collapse column in North China type coalfield is developed and distributed in shallow part of coal well and is non- uniform, so its impact on the coal mine safety is large, and the research and analysis on its development has important theoretical and practical significance for coal mine safety. This paper expounds the the basic conditions and distribution law of karstic collapse column in North China type coalfields, studies and summarizes the morphology, distribution, water cut and water features of the revealed karstic collapse column, and discusses its origin and types.
