同煤忻州窑矿西一盘区石楞成因探讨

Study on Corrugated Coal Seam in First Panel in West in Xinzhou Mine of Datong Coal Mine Group

根据同煤忻州窑矿在西一盘区开采侏罗系大同组煤层时,揭露的石楞的形态与产状、岩性特征及分布范围,对其定义,并指出其与井下生产揭露的冲刷及岩墙的区别,以大同煤田区域地质构造特征和井田地质构造特征为依据,对石楞成因进行分析研究。

This paper gave the definition of corrugated coal seam based on the morphology and occurrence, lithology characteristic, and distribution of uncovered corrugated coal seam in mining Jurassic Datong group coal seam in first panel in west Xinzhouyao Mine, and pointed out the difference of corrugated coal seam and erosion and dykes under the coal mining process. Analyzed and studied causes of corrugated coal seam based on geological structure of Datong coalfield area and tectonic features of underground mine field.
