山西曹村井田岩溶陷落柱发育特征

摘要

The developed Karst collapse column in coalfield Cao village, Shanxi has become the important factors affecting coal production. Karst Collapse Column's growth characteristics are analyzed in the paper from aspects on its spatial form and cylinder characteristics and its influence on the wall rock in coalfield. It is concluded that collapse column is mainly in oval shapes, but is also highly irregular, with different cross-sectional areas, profile shape not very regular. This paper summarized the associated structure of karst collapse column and characteristics of collapse column in tree-shape. This paper helps to find out the development regularities of karst collapse column in coalfield of Cao village, and predict the growth of karst collapse column, has guiding significance for rational arrangement of coalface.%山西曹村井田岩溶陷落柱十分发育，已成为影响煤矿生产的重要因素。从该井田岩溶陷落柱的空间形态、柱体特征、对围岩的影响等方面对其发育特征进行了分析，得出陷落柱平面形态虽以似椭圆形为主，但也是极不规则的，截面积大小不等，剖面形状不很规则。总结了岩溶陷落柱伴生构造和树形陷落柱形态特征，有助于找出了曹村井田岩溶陷落柱的发育规律，预测岩溶陷落柱，对采煤工作面合理布置具有指导意义。
