Research on Inpit Dumping Height during Tracing Mining Period between Two Adjacent Surface Coal Mines

Abstract

When two adjacent surface mines are simultaneously mined in the same direction with a certain relationship of the time and space, the mining arrangement of the former mine will greatly affect the mining plan and economic benefit of subsequent surface mine. In this paper, the optimized mathematical model is established with the mining conditions and economic benefits taken into account. e minimum cost of objective function is analyzed in the condition of considering the different transportation distance with different dumping amount and secondary stripping amount. At the end of this paper a conclusion is drawn that the reasonable dumping level is determined as 1130 based on the annual planning project location and stripping amount, which will reduce the cost of production and smooth the coal mining. Moreover, it is verified by an example to be correct that the mathematical model can be used to solve similar problems of tracing mining or adjacent districts mined in surface mines.

Geotechnological Foundations of Recreational Reclamation of the Kharbalakh Quarry

“…Как правило, сплошные системы разработки с внутренним отвалообразованием применяются при горизонтальном или пологом залегании месторождения с коэффициентом заполняемости выработанного пространства (К з ) равным 1, при котором выработанное пространство полностью заполняется вскрышными породами. При этом в основном используются сплошные и углубочно-сплошные системы разработки с поперечным и продольным размещением фронта горных работ, которые обеспечивают землесберегающий способ разработки месторождения [9][10][11][12]. Как показала практика, данная технология значительно повышает эффективность открытой угледобычи и максимально снижает экологическую нагрузку на окружающую среду.…”

Hybrid Model for Optimisation of Waste Dump Design and Site Selection in Open Pit Mining

“…Sari and Kumral [32] developed an MIP-based model to maximise the Net Present Value (NPV) of the mining project, which, Minerals 2023, 13, 1401 3 of 22 in addition to external dumping, supports a waste dumping option within the same pit. Peng and Zhang [33] developed a mathematical model to determine the optimal height of the internal waste dump and minimise costs.…”
