摘要:

为了确定出倾斜煤层纵采合理移设步距, 以新疆准东露天矿为背景, 揭示了倾斜煤层破碎站移设现状的不足之处, 阐释了破碎站移设研究的改进方向, 分析了单、双破碎站布置对露天矿开采的影响, 通过破碎站移设步距费用相等法并加入卡车重载上、下坡的影响因素, 构建出多台阶的纵采破碎站移设运费数学模型, 确立了倾斜煤层纵采破碎站移设步距的通用公式, 验证了通用公式的合理性, 提出了端帮同侧分离布置、端帮两侧分台阶布置两种双破碎站端帮布置移设方案,并分析以上两种方案的优劣势选出端帮两侧分台阶布置为最优的布置移设方案, 根据该最优的布置移设方案以准东露天矿的开采参数及参考其他露天矿的指标, 计算出两破碎站在端帮纵采移设时合理的移设步距分别为481 m、492 m, 验证双破碎站端帮台阶间移设时带式输送机布置的合理性。

Abstract:

In order to determine the reasonable relocation step distance for vertical mining of inclined coal seams, with an open-pit mine in Xinjiang as the background, the shortcomings of the current situation of the relocation of the inclined coal seam crushing station were revealed, and the direction of improvement in the research on the removal of crushing stations was explained. , The impact of the layout of the double crushing station on the open-pit mining, through the method of equalizing the cost of the moving step of the crushing station and adding the influence factors of the vehicle's heavy load up and downhill, a multi-step mathematic model of the moving freight for the vertical mining crushing station is constructed. Established a general formula for the displacement step distance of the vertical mining crushing station in inclined coal seams, verified the rationality of the general formula, and proposed two dual crushing station end-side layout and displacement schemes, and analyzed the advantages and disadvantages of the two schemes to select the best According to the optimal layout and relocation plan, using the mining parameters of an open-pit mine and referring to the indicators of other open-pit mines, the reasonable relocation step distance of the two crushing stations in the end-side vertical mining relocation is calculated. Verify the rationality of the layout of the belt conveyor when moving between the steps of the end of the double crushing station.
