露天开采工艺参数优化问题中,采用常规优化解法要求构建适于求解的模型形式,但往往存在工程问题建模、求解的困难。针对以上问题,提出工艺参数的仿真求解方法,其核心思路为“确定系统逻辑流程—提取底层驱动事件—确定仿真类型与时钟模拟方法—构建系统状态量化模型—简化控制逻辑—构建驱动事件量化模型—系统重演”。以黑岱沟露天矿无倒堆工艺为案例进行了应用研究,将倒堆系统逻辑流程做三层分解,得出设备基本作业环节为系统底层驱动事件;提出重心圆投影法简化系统控制逻辑,构建了以三维模型为基础的系统存储状态模型;选取离散事件系统建模,利用事件步长法推进仿真进程。仿真结果显示,拉斗铲作业平盘高度在13m附近时其效率最高,当仿真修正系数α取0.94时,误差最小。

In the parameters optimization of surface mining process, it is necessary to construct a suitable model for solving the problem by using the conventional optimization method. However, there are often difficulties in modeling and solving problems in engineering problems. Aiming at this, the simulation method of process parameters is proposed, The core idea is “ to determine the logic flow of the system - to extract the underlying drive events - to determine the simulation type and clock simulation method - to build the system state of the quantitative model - simplify control logic - build drive event quantization model - replay system”. the application of the overcast stripping technology in Heidaigou Surface Mine is studied, the logic flow of the system is decomposed into three layers, the basic operation of the equipment is the driving event of the system; the center of gravity circle projection method is proposed to simplify the system control logic, and the system storage state model based on the three-dimensional model is constructed; The discrete event system modeling is selected and the simulation process is advanced by the event step method. The simulation results show that the system efficiency is maximized when the bench height is m, and the error is minimized when the simulation correction coefficient is 0. 94.
