摘要

摘要: 煤矿井下排水系统的工作效率直接影响到煤矿的生产安全和经济效益。现有矿井多级接力式排水系统对于电费波峰波谷特性和《煤矿防治水细则》要求的排水系统安全约束考虑不全面，难以实现整体系统的一体化安全经济运行。针对该问题，基于避峰就谷策略和动态规划方法，提出分时电价下矿井多级接力式排水系统的优化策略。通过考虑煤矿排水系统的多级串联结构、涌水量和水泵的排水能力，建立了煤矿多级接力式排水系统的数学模型。基于避峰就谷策略，以电费成本最低为目标函数，以水仓水位、水泵排水能力、煤矿安全要求等为约束条件，构建基于分时电价的多级接力式排水系统优化问题，并给出了基于动态规划方法的求解算法。以某矿井4级排水系统为例进行仿真分析，结果表明，该策略可有效控制井下水位，保证水位处于合理高度：当电价较高时，水泵开启的数量很少或为零，水仓处于高水位状态；当电价较低时，水泵开启的数量较多，水仓处于低水位状态。该策略能够在提升经济效益的同时，保障煤矿的生产效率和生产安全。

Abstract: The efficiency of the underground drainage system in coal mines directly affects the production safety and economic benefits of coal mines. The existing multi-level relay drainage system in mines does not fully consider the peak and valley features of electricity bills and the safety constraints of the drainage system required by the Coal Mine Water Prevention and Control Regulations. It is difficult to achieve integrated safe and economic operation of the entire system. In order to solve the above problems, based on the avoiding peaks and filling valley strategy and dynamic programming method, an optimization strategy for multi-level relay drainage system in mines under the time of use electricity price is proposed. By considering the multi-level series structure, water inflow, and drainage capacity of water pumps, a mathematical model of a multi-level relay drainage system in coal mines is established. Based on the strategy of avoiding peaks and filling valleys, with the lowest electricity cost as the objective function and constraints such as water level in water tanks, drainage capacity of water pumps, and coal mine safety requirements, a multi-level relay drainage system optimization problem based on time of use electricity price is constructed. The solution algorithm based on dynamic programming method is provided. Taking the 4-level drainage system of a certain mine as an example for simulation analysis, the results show that this strategy can effectively control the underground water level and ensure that the water level is at a reasonable height. When the electricity price is high, the number of drainage pumps opened is very small or zero, and the water tank is in a high water level state. When the electricity price is low, the number of drainage pumps opened is larger, and the water tank is in a low water level state. This strategy can improve economic benefits while ensuring the production efficiency and safety of coal mines.
