摘　　要：由于岩浆的侵入破坏作用,使得煤层结构复杂化,煤、天然焦和岩浆岩交叉混合在一起,降低了煤层和天然焦的可采性,开采条件变复杂。一直以来天然焦伴随煤炭一起勘查,其勘查线距也遵从煤炭相关规范,而实际开采天然焦采区的设计与井下实际的采区布置相差较远。以安徽淮北天然焦矿井为例,对该矿的探采对比情况进行探讨,认为勘探阶段针对天然焦矿层勘探钻孔间距和勘探线距,无法满足矿井实际开采需要,适宜的勘查工程线距至少为50~100m。Because of magmatic intrusion and destruction make coal seam structure complicated; coal, natural coke and magmatic rock mixed-up can reduce coal and natural coke recoverability, and make mining condition complex. All along, natural coke exploration keeps in company with coal, its exploration lines spacing complying with relevant specifications. But actually, the natural coke productive workings design and underground arrangement vary greatly from coal mining. Taking a natural coke mine in Huaibei, Anhui as example carried out correlation of exploration and mining information of the mine. The result has considered that the original determined borehole spacing and exploration line spacing can not satisfy actual mining requirement, while appropriate exploration line spacing should be at least 50~100m.
