三软薄煤层智能化工作面开采技术及装备的设计与实践

Design and Practice of Integrated System for Intelligent Unmanned Three Soft Thin Coal Seam Working Face Mining System

针对朔里矿业公司II415工作面破碎顶板、三软、1.35 m薄煤层,通过多次调研,应用高清摄像仪、高精度行程传感器、压力传感器、高精度煤机位置定位、高精度采高传感器、测高传感器完成数据采集,构建三层网络架构完成信息流交互,结合现场实际调整支架及煤机自动化动作程序,实现复杂地质条件下的煤机记忆截煤、支架跟机联动、跟机自动推移刮板机等一系列自动化远程作业,泵站系统、后运系统无人连锁控制。该系统具备70万t/a以上的生产能力。

Aiming at II415 working face′s cracked roof, 1.35 m thin three soft coal seam in the western mine of Shuoli company, several surveys were conducted to collect data by using HD camera, high precision travel sensor, pressure sensor, high precision coal machine position positioning, high precision mining sensor, height sensor. Based on the the analysis of the data, proposed a three network construction of information flow, in order to achieve the automate remote work in terms of intelligent cutting coal mining, hydraulic support with linkage system, automatic passage flight conveyor, pump station system and unmanned systems under complex geological conditions. The system has an annual production capacity of 700,000 t/a.
