Essay

The dissertation is devoted to the study and establishment of regularities of the surface displacement above moving stope. The methods of geometrical simulation and analysis of subsidence trough surface above driven stope of a flat coal seam are developed. The regularities of a geometrical structure of a subsidence trough surface above coalface are established. It is proved that its complete constitution is determined by surface subsidence's distribution in the special section. This section is called a basic section of a dynamic trough. The regularities of a basic section's profile formation of a dynamic trough and trough surface as a whole are determined depending on conditions of a surface underworking. The geometrical schemes of subsidence troughs from mining of double longwalls and longwalls in contiguous seams are designed. These schemes provide the least deforming of the surface and make it possible to control by displacement process
