摘要
通过云南镇雄县牛场、以古煤矿区含煤地层岩性组合特征、沉积结构、构造、含煤岩系主要沉积相分析,研究了区内的主要煤层沉积特征,从而进一步对影响区内主要煤层厚度变化的主要因素及变化规律分析研究。
Through analyzing the lithologic characteristics, sedimentary structure, tectonic, coal-bearing rock series main sedimentary facies of coal bearing strata at Niuchang and Yigu mining areas in Yunnan Zhenxiong, the author researches the main sedimentary characteristics of coal seam and analyzes main factors and change rules of affecting main coal seam thickness change in mining areas.
