摘要:

针对综采工作面采煤机运行中存在的电能浪费与采煤生产率低下的问题,文章提出一种基于截割阻抗预测的采煤机“能”与“效”协同优化方法,旨在实现采煤机的高效节能运行。首先,为应对综采工作面复杂多变的运行工况,采用优化后的径向基神经网络(SPSO-RBF)对采煤机截割阻抗进行精准预测;其次,通过分析采煤机运行过程中的阻力,构建基于截割阻抗的能耗模型;进一步,采用基于自适应旋转模拟二进制交叉的非支配排序遗传算法-Ⅱ(NSGA-Ⅱ+ARSBX),建立以能耗最小化、采煤生产率最大化与块煤面积最大化为目标的多目标优化模型,求解得出优化的采煤机牵引速度和滚筒转速;最后,依托锦界煤矿采煤机数据开展工程案例验证。结果表明,在割一刀的工艺流程下,优化后能耗降低20.04%,采煤生产率提升45.71%,块煤面积增加41.56%,验证了所提模型和算法的正确性与有效性。

Abstract:

Under the strategic backdrop of the “dual carbon” goals, the low-carbon transformation of the coal mining industry is now urgent. Addressing the issues of energy waste and low coal production efficiency caused by the operation of coal cutters in fully mechanized mining faces, this paper proposes a method for the synergistic optimization of energy efficiency and operational effectiveness of coal cutters based on cutting resistance prediction, aiming to achieve efficient and energy-saving operation of coal cutters. First, to address the complex and variable operating conditions in fully mechanized mining faces, an optimized radial basis function neural network (SPSO-RBF) is employed to accurately predict the cutting resistance of coal cutters; second, by analyzing the resistance encountered by coal cutters during operation, an energy consumption model based on cut-ting resistance is established; furthermore, the non-dominated sorting genetic algorithm-II (NSGA-II+ARSBX) based on adaptive rotary simulated binary crossover is used to establish a multi-objective optimization model with the objectives of minimizing energy consumption, maximizing coal production efficiency, and maximizing block coal area, and the optimized traction speed and drum speed of the coal miner are obtained; finally, engineering case verification is conducted based on coal miner data from the Jinjie Coal Mine. The results show that under the one-cut process, energy consumption is reduced by 20.04%, coal mining productivity is increased by 45.71%, and the area of lump coal is increased by 41.56%, verifying the correctness and effectiveness of the proposed model and algorithm.
