Type of crossing of coal waste dumps by geodynamical dangerous zones

Abstract

The paper develops the concept of the existence geodynamically dangerous zones in the earth’s crust. These zones affects to the safety of the state of engineering structures and mining operations. The concept of geodynamic zoning is used, according to which geodynamically dangerous zones occurs during the interaction of blocks of the earth’s crust of various hierarchical ranks. On the example of the East Donbass, the typification of the intersection of coal waste dumps with geodynamically dangerous zones is considered. The position of 34 burning and burnt out dumps located near the cities of Shakhty and Novoshakhtinsk, Rostov Region, their size R and the width of geodynamically dangerous zones r are taken in account. Based on the use of geodynamic zoning data, an analysis is made of the nature of the mutual arrangement of carbon rock dumps and the boundaries of blocks of the earth’s crust (geodynamically dangerous zones). It is found 4 types of intersection of the block boundaries and the body of the dumps. The intersection of the first type occurs when R> r and the location of the intersection site entirely under the dump. The intersection of the second type occurs when R <r and the location of the dump entirely in the geodynamically dangerous zone. The intersection of the third type occurs at any ratio of R and r, but the common area overlaps the geodynamically dangerous zone only partially (touch). In the fourth type of intersection, the set of common points R and r is empty (do not intersect). Typification can be used when choosing places for dumping and computer modeling of their thermal state.
