大采高智能化工作面液压支架自动跟机控制技术研究

Research on automatic follow-up control technology of hydraulic support in intelligent working face with large mining height

大采高工作面支护作为安全高效开采的核心,伴随智能化工作面不断的实践探索,液压支架的时-空运动、支护效果更是首要条件,因此对液压支架在智能化工作面的应用进行了研究,以陕西黄陵二号煤矿有限公司416大采高智能化工作面为背景。通过地质条件分析、支架与围岩关系、理论分析、生产工艺等,最终确定选用国产ZY10800/28/63D型掩护式液压支架。基于对智能化元件的逻辑,支架时-空运动指标分析、调试,优化支架SAC系统的时间属性。完成了SAC系统与采煤机、刮板输送机的自动根机拉架和自动成组推移刮板输送机作业等主要动作,形成液压支架群组的自组织协同控制方法。液压支架的协调控制实现了工作面的智能开采。建立了符合矿井工作面的液压支架智能化标准,有效地保证了大采高智能化工作面"和谐-安全-高效"生产。

With the advance of intelligent mining face,the core of safe and high-effective mining is the support of faces with large mining height and the primary condition is the time-space movement and supporting effect of hydraulic support.To study the application effect of hydraulic support on intelligent mining face,this thesis takes intelligent mining face with large mining height No.416 at No.2 Coal Mine of Huangling Mining Group as an example.The author analyze geological condition,relationship between supporter and surrounding rock,and introduce production process,as well as theoretical analysis which altogether contributes to the choose of ZY10800/28/63 D hydraulic support.Based on the logical of intelligent element,the time attribute of SAC system is optimized through the analysis of support timespace movement.SAC system is combined with shearer and scraper conveyor which altogether realize the cooperative control of hydraulic supports.Cooperative control of hydraulic support makes intelligent mining possible.The establishment of standard of intelligent hydraulic support system,which in accord with condition on working face,ensures the harmony,safety and efficiency production of intelligent mining face at mid-deep large height mining.
