Currently, in developing the most inclined and steep coal deposits in the Central and Northern Kuzbass (Western Siberia, Russia), the deeping longitudinal open pit mining method is used with overburden rock moved to external dumps using transport technology. One of the ways to reduce the rate of land withdrawal while reducing development costs by shortening the distance of overburden movement is to use block lateral mining method with overburden storage in the worked out space. The paper emphasizes that well-known technological solutions consider quarry fields untouched by mining, or in the process of exploitation, so the block mining procedure is using fragmentally along with moving overburden by dump trucks. Internal dumping, as an element of land preservation, has not been generally considered to date. This is a deterrent to the implementation of resource-saving mining technologies, both in design and mining practice.
