摘要

为保证顶板破碎段工作面端头支护强度,对工作面回采期间端头应力分布进行分析。提出利用打设锚杆、锚网索的方式进行主动支护,利用掘进期间架设工字钢棚,在回采前打设边路抬棚和中路抬棚,在回采时加强对中路抬棚交替迈步复合支护方式,提高了端头支护的强度。
        In order to ensure the end support strength of working face in broken roof section, the stress distribution at the end of working face during mining is analyzed. It is proposed that active support should be carried out by means of setting up the bolt-mesh-anchor, and I-shaped steel shed should be erected during excavation. Set up side-way and middle-way carrying framed timbers before stoping. The composite support is strengthened by means of alternating steps of middle-way carrying framed timbers in the process of stoping. The strength of end support is enhanced by composite support.
