| 摘 要： | 通过对淮北煤田闸河矿区永固井田岩浆岩发育特征的剖析，探讨了其形成机理，发现该井田岩浆侵入具有“倒贯”、波动性、选层性等特征．在此基础上，进一步采用趋势面分析方法，对３煤层厚度与岩浆岩厚度之间的关系进行了研究，预测了厚煤区的展布位置，求取了煤炭储量，成果对采区布置具有一定的指导意义．

| Abstract: | Based on the studies of the characteristics of magmatic rook in the Yonggu mine, Zhahe mining district, Huaibei coalfield, the mechanism of intrusion and the origins such as inverted, impulsed and selective intrusions are discussed. Furthermore, the relation between the thickness of coalbed No.3 and that of magmatic rock is analysed using the method of trend surface analysis, and then the distribution of thick coalbed zones and the coal reserves are evaluated. The results might be applied in some degree to the mining layout in the coal mine. |
