介绍了一种应用切顶泄压短悬臂梁留巷矿压理论,全新思路的沿空留巷支护方式—切顶留巷成套支护设备,切顶留巷成套支护设备是一种具有支护、防护、挡矸、切顶、清矸、铺设立网及导网、自移自调等多种功能的,适用性强、适用范围广的全新型留巷支护设备,包括留巷端头支架和留巷切顶支架两部分。该设备的应用比传统的沿空留巷支护方式投资少、操作简单、安全可靠、可完全重复利用,是当前无煤柱沿空留巷开采较为先进有效的支护方式。
A kind of supporting method of gob-side entry retaining and retaining roadway with top-pressure relief short cantilever beam retaining alluviation theory and new ideas is introduced. Support, protection, block rock, cut top, clear rock, the laying of the net and the guide wire, self-tuning and other functions from the self-tuning, adaptability, wide application of the new type of retaining lane retaining equipment, including retaining Lane End bracket and stay Lane cut top bracket two parts. The application of this equipment is less investment than the traditional gob-side entry retaining method, which is simple, safe and reliable, and can be completely reused. It is a more advanced and effective support method for the mining of gob-side entry retaining without pillars.
