Industrial research into massif zonal fragmentation around mine workings

What is it about?

Purpose. The main purpose of the work is identification of massif zonal fragmentation around mine workings by means of industrial methods of research. Methods. Research of processes of massif zonal fragmentation around mine workings was carried out by means of natural experiments with usage of methods of supervision and estimates, mine surveying, massif unloadings, deformation of wells and deep bench marks. Findings. In industrial conditions, results of research of massif behavior around mine workings allowed to define the steady relation of fragmentation depth of the massif are received. It is established that the form of destruction of a contour of preparatory and stoping w aspired to workings led to ellipsoidal, the steadiest form of mine working. Change of depth of massif deformation on a contour of stoping chambers is realized general-ly on exponential functional, and in adjoining preparatory workings, more on exponential. Originality. It consists in systematization of processes of massif zonal fragmentation around mine workings for the purpose of rock pressure usage in technologies ore deposits mining. Practical implications. The steady form of preparatory and stoping workings contour destruction is defined and dependences of deformation depth changing of the massif that containing workings are established.
