摘　　要：通过对该区遵义煤矿、桐梓煤矿、泮水煤矿和凤岗煤矿的煤矸石进行X衍射分析,初步查明了该区煤矸石的矿物成分及变化规律。结果表明,该区煤矸石矿物成分明显受含煤地层的岩石类型控制,普遍含有大量的粘土矿物和一定量的锐钛矿,粘土矿物含量受含煤地层的岩石类型、风化作用、堆放位置和堆放时间等因素的影响;锐钛矿受风化作用的影响较小、易于分选,是煤矸石中稀有、稀土、贵金属等价值很高元素的赋存矿物,在综合利用,尤其是经济价值更高的高端利用中应给予重视。With the X ray diffraction analysis conducted on the coal rejects from Zunyi Mine,Tongzi Mine,Panshui Mine and Fenggang Mine in the area,the mineral composition and the variation law of the coal rejects in the area was preliminarily proved.The results showed that the mineral composition of the coal rejects in the area were obviously controlled by the rock type of the coal-bearing strata and would have the great number clay minerals and certain anatase.The mineral content of the clay would be affected by the rock type of the coal bearing strata,weathering action,stacking location,stacking time and other factors.The anatase mineral was less affected by the weathering action and would be easy for the separation preparation.The anatase would be a mineral with high valuable elements,such as the rare metals,rare-earth,precious metal and others in the coal rejects.The great attention shall be paid to the comprehensive utilization of the coal rejects and especially the high level utilization with the higher economic value.
