摘要： 对木瓜煤矿岩溶陷落柱进行分析，研究了岩溶陷落柱的分布规律、地表特征，并对研究区陷落柱的形成原因
与发育规律等做了进一步分析。基于对岩溶陷落柱的分析，与构造演变相结合，提出岩溶陷落柱发育都是地质构造推动
的，而地下水运动作为基本前提，地层岩性组合特征对其具有控制作用，研究区岩溶陷落柱密集形成期确定为中生代。

Abstract: This paper analyzed the karst collapse column in Mugua Coal Mine, studied the distribution rules and surface characteristics
of the karst collapse column, and further analyzed the formation and development rules of the collapse column in the
study area. Based on the analysis of karst collapse columns, combined with structural evolution, it is proposed that the development
of karst collapse columns is driven by geological structure, groundwater movement is the basic premise, and the combination
of stratigraphic lithology features has a controlling effect on it. The formation period of the karst collapse columns densely packed
in the study area is determined to be the Mesozoic.

Key words: karst collapse column; geologic structure; development law
