About company Sand sale Mining Our address Development of flooded fields Development of sand and sand deposits Mining Our company LLC "Dorstroisintez" provides joint cooperation, including such as the development of deposits of common minerals for construction raw materials. At the same time, we undertake the following redistribution of works: Organization of work on geological exploration of the field, approval of reserves, determination of the optimal development option, Design of mining facilities and the implementation of activities for the development of design and technical documentation at existing quarries for the extraction of building sands, Construction of mining facilities (quarries) and technological surface complex of mining enterprises, The actual development of the field, Mine surveying support Assistance in the sale of extracted raw materials, Construction and repair of local roads. The development of deposits is carried out by open, underground and combined methods. The open method is characterized by the fact that the extraction of useful rock, its loading and transportation are carried out on the surface of the earth. With the underground method, all these operations are performed underground. The combined method includes elements of open and closed development. The choice of this or that method of development depends on the quality of the useful rock, the amount of reserves, the depth of occurrence and the conditions of development. Nonmetallic minerals used as building materials or in the form of raw materials for their manufacture, in most cases, are relatively shallow, therefore, industrial deposits of such rocks are developed mainly by opencast mining. Open pit mines in comparison with closed ones have a number of significant advantages both in technical and economic terms, but their significant disadvantage is a significant amount of work associated with the excavation, haulage and dumping of waste rock (overburden), dependence on the climatic and atmospheric conditions of the area, as well as the possibility of massive collapses of the surface layers of the earth in the form of landslides. Подготовка открытых разработок состоит из выбора участка, подготовки поверхности, осушения месторождения и ограждения его от вод, вскрытия месторождения, вскрышных и отвальных работ и работ, связанных непосредственно с добычей и откаткой полезного ископаемого. Основные расходы при открытых разработках падают на добычу полезной породы, вскрышные и отвальные работы. В связи с этим решающим показателем при определении экономической целесообразности считается величина коэффициента вскрыши, выраженного в весовом или в объемном отношениях. Весовым коэффициентом вскрыши называется весовое выражение количества пустых пород, какое необходимо удалить, чтобы добыть одну тонну полезной породы. Объемным коэффициентом вскрыши называется объемное отношение пустых пород, приходящееся на 1 м2 полезной породы. Field development is one of the main directions of our company. We invite partners for the joint development of deposits of common minerals and provide services across the entire spectrum of surveying and geodetic works.
