Abstract:Coal seam appears dislocated when mining encounters a fault, and stripping ratio will drastically change, then mining engineering is difficult to be continued. In order to maintain the stability of stripping and mining, mine engineering transition succession and stripping ratio should be controlled when mining through faults. Mathematic models of mining stripping ratio and coal seam thickness, fault angle and fault throw are built to analyze the impact of different unexploited coal pillar widths on slope stability. The relationship between the pace of development and simultaneous coal mining beach is analyzed and the dynamic drawdown speed is determined to ensure a smooth transition succession in mining engineering. Combing with the surface mine problems that occur in fault area, this paper takes Shengli East No.2 Surface Mine mining through F61 fault as a case study. The results show that the stripping ratio is balanced and the production keeps stability, moreover, the economic benefit is improved with the method of mining through faults and production capacity succession.
