AI Technical Summary

Technical Problem

Existing technologies make it difficult to achieve safe, efficient, and fully mechanized mining of near-vertical medium-thick and thick coal seams, especially due to insufficient working face layout space caused by coal seam thickness constraints, which poses a risk of roof and floor collapse.

Method used

The system employs an adjustable-angle roof support and cross-telescopic support columns, combined with retractable support baffles and base designs, to form a stable triangular support system. Through the support column hinge device and the base embedded in the rock wall groove, the system can achieve flexible adjustment of the support and multi-layer support.

Benefits of technology

This improved the support's anti-slip capability and overall stability in near-vertical environments, reduced the risk of rock wall pressure concentration, and ensured the safety and efficiency of the mining process.

Abstract

本发明公开了一种近直立中厚、厚煤层充填开采支架及方法,属于煤矿开采支护设备技术领域。该支架包括夹角可调的房式支顶,房式支顶下方并排设有多组提供支撑力的交叉伸缩支柱组,交叉伸缩支柱组包括两根三段结构的伸缩支柱,伸缩支柱由上、中、下三段结构组成,上段和下段分别能够相对中段进行轴向伸缩,所有伸缩支柱的上段顶部均与房式支顶连接,两根伸缩支柱的中段处通过支柱铰接装置交叉连接;交叉伸缩支柱组的下段底部设有能够稳定在近直立中厚、厚煤层顶底板之间的底座。该支架可防止充填体或上覆岩层垮落对工作面安全生产的威胁,为解放近直立中厚、厚煤层资源提供了安全保障。
