Abstract
The invention discloses an overall support device for a large dip angle coal roadway and a usage method of the overall support device for the large dip angle coal roadway. The overall support device comprises two wall protection steel boards which are connected through a lockable rotation assembly, the overall support device is adjusted according to the angle between a roadway top board and a roadway sidewall before being installed, the included angle between the two wall protection steel boards of the overall support device is made to be in accord with the included angle between the roadway top board and the roadway sidewall, and locking bolts are utilized to penetrate through fixed locking holes in the rotation assembly and rotation shaft locking holes in a rotation shaft to rotate and fix the overall support device. Anchor stocks (anchor cables) are used for fixing the overall support device on the roadway top board and the roadway sidewall, and the overall support is formed. The overall support device is simple in structure and practical, and the top board and the sidewall of the fragile large dip angle coal roadway are integrally supported while the functions of wall protection and connection of a traditional steel belt are achieved.
Description
Technical field
The present invention relates to mine timbering Material Field, be specially a kind of high inclination-angle coal road integer support device and using method thereof.
Background technology
Bolt support is widely used in ground and mining engineering with its significant techno-economic effect.In adopting the engineering of bolt support, most steel bands that use, as protecting table attachment, retrain with the country rock between anchor pole, improve the supporting capacity of country rock self.But when traditional steel band is used, be generally side top separated (a side wall supporting, topmast is protected top), easily cause the distortion of fillet place, tunnel greatly, high inclination-angle coal road especially, even unstability more easily deforms.
Summary of the invention
The object of the invention is to exist the separated supporting in side top, high inclination-angle tunnel to cause the excessive and problem of wall caving very easily of fillet distortion for prior art, a kind of device and supporting method with integer support ability is provided.
To achieve these goals, the present invention is characterized in that: described high inclination-angle coal road integer support device mainly comprises steel plate A(1), steel plate B(2), rotating member (3), bolthole (4); Described steel plate A(1) with steel plate B(2) through rotating member (3), be connected and adjustable angle; The fixedly locked hole (5) that described rotating member (3) can utilize lock(ing) bolt to pass on rotating member is fixing to this device rotation with the axis of rotation lock hole (10) on axis of rotation (9); Described steel plate A(1) with steel plate B(2) length can make according to tunnel size; The using method of described high inclination-angle coal road integer support device of the present invention, first according to this globality suspension device of angle adjustment between back and portion of side, make side angle in two retaining wall steel plate angles of this device and tunnel top consistent, the axis of rotation lock hole (10) that utilizes lock(ing) bolt to pass (9) on fixedly locked hole (5) on rotating member (3) and axis of rotation is fixed this device rotation.With anchor pole (anchor cable), this device is fixed on back and rib, forms integer support.
The present invention has improved high inclination-angle coal road high side angle tradition support pattern, the side separated supporting in top while having overcome traditional steel band use, cause the excessive and problem of wall caving very easily of fillet distortion, neoteric suspension device is using high inclination-angle tunnel top side as an integer support, Surrounding Rock Control that can extensive use high inclination-angle coal road.
