千米煤矿深井中特大型箕斗的应用能够有效提高生产效率，但是随着箕斗体积和容量的持续增加会对传统钢丝绳矿井提升方式提出挑战，产生钢丝绳强度不足、寿命减少以及安全性降低等问题。针对传统钢丝绳提升箕斗时面临以上问题显露的不足，以煤矿千米深矿井作为工程背景，提出了一种采用垂直式永磁直线电机辅助驱动的特大型箕斗提升方案，能够在目前载重最大50 t箕斗的基础上再增加20%载重。首先，对辅助提升系统涉及的总体提升方案、矿井布置与选择、箕斗结构及增量设计、辅助提升电机结构设计等问题依次进行分析；其次，详细阐述了一种主从控制和并行控制相结合的控制策略，能够实现多种电机对箕斗的协同驱动，保证该辅助提升系统能够稳定运转；最后，利用MATLAB/Simulink建立了垂直式永磁直线电机辅助提升系统的单元电机和多电机矢量控制仿真模型，分析了该系统在匀速、速度突变以及制动工况下速度和推力的变化情况。结果表明，单元电机在恒速变负载情况下具有电机响应速度快、电机推力和速度变化稳定等特性；多电机控制模型在匀速和速度突变情况下主从电机速度以及输出推力跟随状况良好；辅助提升系统若采用主从速度跟随控制策略，难以在突发情况下及时稳定地进行制动，故在系统制动时应采用并行式同步控制策略。考虑到千米深井运行工况复杂，该仿真模型虽有所简化，但仍具有足够优良的同步跟随性和稳定性，研究结果对超深矿井特大型箕斗提升系统的设计开发具有重要理论价值和实际意义。

In the kilometer-deep coal shaft, the application of extra-large skips in deep mines of 1 000 meters can effectively improve production efficiency, but with the continuous increase of skip volume and capacity, the traditional method of steel wire rope mine hoisting will be challenged and it will cause hoisting rope strength insufficient, the reduce of the service life and the reduce of the security. In view of the shortcomings of the traditional method of steel wire rope lifting method, this paper takes a thousand-meter-deep coal mine as the engineering background, and proposes a super-large skip-lifting scheme using a vertical permanent magnet linear motor assisted drive, which can lift the skip at the current maximum of 50 t.Firstly, the overall hoisting scheme, mine layout and selection, skip structure and incremental design, auxiliary hoist motor structure design involved in the auxiliary hoisting system were analyzed in turn; Secondly, a control strategy combining master-slave control and parallel control was described in detail, which can realize the cooperative drive of multiple motors to skip, and ensure the stable operation of the auxiliary hoisting system. Finally, the unit motor and multi-motor vector control simulation models of the vertical permanent magnet linear motor-assisted hoisting system were established by MATLAB/Simulink, and the changes of speed and thrust of the system under constant speed, sudden speed change and braking conditions were analyzed. The results show that the unit motor has the characteristics of quick response, stable change of thrust and speed, high running accuracy under the condition of constant speed and variable load; the multi-motor control model has accurate performance in speed and output thrust following under constant speed and mutation speed; when the system adopts the master-slave speed following control strategy, it is difficult to brake stably in time under the sudden situation, so the parallel synchronous control strategy should be adopted in the system braking; considering the complexity of the actual working conditions in the kilometer-deep mines, although the simulation model is simplified, the system has sufficient synchronization and control stability. The research results have important theoretical value and practical significance for the design and development of extra deep shaft hoisting system.
