COLLIERY. PLATE CLAY. Fig. 1. Section on the line of dip and rise, showing the general effect of the overlying strata upon the buildings.Scale 6 feet to an inch. Fig. 2. LONGWALL METHOD OF WORKING COAL Fig. 1. Scale 60 yards to an inch. LIFTING PUMPS. Fig. 2. This diagram shows two lifting pumps installed in a colliery. The pumps are mounted on a horizontal platform at the surface. Each pump consists of a vertical shaft that extends down into a vertical shaftway. The shafts are connected to a common horizontal beam at the top, which is supported by a triangular frame structure. The shafts are shown with various mechanical components, including what appear to be valves or strainers, and they terminate in a central shaftway that leads down into the ground. This diagram provides a detailed view of the lifting pumps installed in a colliery shaftway. The shafts are shown extending from the surface down into the shaftway, which is lined with a material (possibly brick or stone). The shafts are equipped with various mechanical components, including valves, strainers, and a central shaftway that leads down into the ground. The shafts are shown with various mechanical components, including what appear to be valves or strainers, and they terminate in a central shaftway that leads down into the ground. FORCING PUMPS. Fig. 1. This diagram shows forcing pumps installed in a colliery shaftway. The pumps are mounted on a horizontal platform at the surface. A vertical shaft extends from the surface down into the shaftway. The shaft is connected to a horizontal beam at the top, which is supported by a triangular frame structure. The shaft is shown with various mechanical components, including what appear to be valves or strainers, and it terminates in a central shaftway that leads down into the ground. The shaftway is lined with a material (possibly brick or stone) and has a central shaftway that leads down into the ground. Fig. 2.
