综采工作面两巷超前支护是为了确保工作面上下出口的畅通而采取的特殊加强支护；综采工作面运输巷超前支护段设备布置密集，是行人、通风及输送煤炭咽喉；大采高综采工作面运输巷断面大，常规的单体液压支柱超前支护已经难以适应工作面安全高效的需求。 本文以红柳林煤矿5-2号煤层15206等大采高综采工作面运输巷采用自移式超前支架护为具体研究对象，在分析大采高综采工作面回采过程中运输巷围岩变形破坏特征和ZLJ2X1960/32/46型运输巷自移式超前支架结构形式特点的基础上，根据运输巷断面和转载机、破碎机等设备配套尺寸要求分析了运输巷超前支架的主要结构尺寸适用性，通过工程类比和理论分析分析了运输巷自移式超前支架支护强度的合理性，结合现场试用对超前支架进行了进一步改进完善，试验采用了电液控制以提高超前支架在操作的自动化程度，通过现场实测研究了超前支护主要工序时间，得到了运输巷自移式超前支架的合理工序安排。现场应用表明应用交错迈步自移式超前支架结构及参数合理、自稳能力强、自动化程度高、支护速度快，显著改善了综采工作面运输巷超前支护状况，提高了人员作业的安全性，经济和安全效益显著。

In order to ensure unblocked haulage roadway and air-return roadway, Special reinforced support have been adopted in fully-mechanized face. Equipments are intensive in the haulage roadway of large mining height fully-mechanized face, and the haulage roadway is key position of pedestrian, ventilation and transportation. Because section is more bigger, The traditional single hydraulic prop has not meet fast mining, safety and high efficiency. In this paper, the research object is the ahead self-shift advanced support for the haulage roadway ,which is used in 5-2 coal seam,15206 working face in HongLiulin Coal Mine. Based on the analysis of distortion and failure characteristics of surrounding rock around haulage roadway in large mining height fully-mechanized face and structure character of ZLJ2X160/32146 self-shift advanced support , and according to the requirement of main structure sizes of matching transfer machine and crusher, we analyzed the applicability of main structure sizes of ahead support . The support strength is determined through theoretical calculation and engineering analogy, the ahead support is improved through field test to a large degree. In the meantime, based on electro-hydraulic control, the automation degree is improved. The time of main procedure is determined by field measurement, and reasonable procedure arrangement of ahead support is designed. The engineering practice shows that structure and parameters of ahead support are reasonable, self-stable ability is reliable enough to work normally, automation degree and support rate are enhanced. The safety of roadway near working face is improved. Worker's labor intensity and cost are reduced significantly, economic and safety benefits are improved remarkably.
