The combined method of horizontal wells development by a soil thrust boring plant of static action with cutting rings has been proposed. The ratio between the diameters of the cutting ring and horizontal well has been determined. The regression equation was received to determine a minimum depth of a horizontal well laying depending on the diameter of the bore hole and soil porosity. The dependencies for determining emerging forces while developing a horizontal well with a cutting ring and its cleaning with a disk with account of geometric parameters of the working equipment and soil condition have been established. The general view of the soil thrust boring plant and its working equipment for developing horizontal wells has been presented.
