切顶留巷成套支护设备的研究与应用

Research and Application on Complete Set of Roof-cutting Roadway Retained Supporting Eequipment

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。

Introduces a complete set of roof -cutting roadway retained supporting equipment which applies the mining pressure theory of roof-cutting pressure relief short cantilever beam roadway retained and brand new thought of gob-side entry supporting mode . The equipment is a brand new type of supporting equipment which consists of two parts, i.e. the roadway retained gate end roof support and roadway retained roof-cutting roof support. It has integrated multiple functions of supporting, protecting, waste rock blocking, roof -cutting, gangue clearing up, laying net and guiding net, self moving and adjusting, has good applicability and wide range of application. Compare with the traditional gob-side entry supporting mode, it has the advantages of small investment, easy operation, safe and reliable and reutilization. At present, it is the most advanced supporting mode for gob-side entry retaining mining without coal pillars.
