    SOME PROBLEMS OF KARSTIC COLLAPSE POSTS IN NORTH CHINA TYPE COALFIELDS

    • Karstic collapse posts existing in North China type coalfields is a special kind of karstic collapse. Based on the special investigation of collapse posts in coalfields of northern China, this paper summarizes their space distribution regularities, gives index system for macroscopic prediction of the collapse posts. By the view point of production, the authors analyze the factors related to water conducting behavior, generalize the method to determine the ground water runoff belt, discuss three types of conduits, and analyze the discrimination of collapse posts and difference between water bursting caused by collapsed posts and that caused by faults.
