摘要
Magmatic intrusion has great effect on coalmine production. The Wolonghu coalmine in the Huaibei coal field is one of those severely affected by magmatic intrusion,where geological structure is major factor controlling magmatic intrusion and distribution of magmatic rocks. The Wolonghu coalmine has been subjected to intermediate magmatic in- trusion since Jurassic as a result of intensification of magmatic activities, and it largely invaded into the roof, floor or between seams. Based on distribution of magmatic rocks disclosed by drilling, this paper analyzed the data and conclud- ed that the magmatic intrusion is confined by form, structure, physical and chemical nature and occurrences of the coal seams.
