| 摘 要： | 对祁东煤矿32、61、9三个煤层的煤质变化特征及其主要影响因素进行分析，结果表明：从32、61到9煤层，煤的挥发分明显减少，而粘结指数略有增加，煤质呈现有规律的变化，从气煤和气肥煤向1／3焦煤和肥煤方向转化。同时，9煤层出现挥发分急剧减少、粘结性完全丧失的热变煤。分析认为：祁东煤矿从32、61到9煤层，从无到有、从弱到强的岩浆侵入活动是形成煤质变化的主要原因，区域岩浆热变质作用导致了这三个煤层煤质的规律性变化，而接触变质作用导致了9煤层热变煤的形成。 |

| Abstract: | Coal property change of coalseams No.32,61 and 9 in Qidong coalmine and its mayor controlling factors are studied.The results showed that: from coalseam No.32,61 to 9,volatile matter in coal obviously decreases while caking index slightly increases,coal property regularly changes from gas coal and gas-fat coal to 1/3 coke coal and fat coal.In coalseam No.9 thermo-metamorphic coal occurrs with sharply decreased volatile matter and with no caking property.The research showed that: the magmatic intrusion in Qi... |
