Chapter 1.0 Introduction

Van der Merwe and Madden, (2002) state that because of the long free length of the steel tendon, mechanical anchor bolts can stretch when load is applied. It is therefore a soft support, even though it is active by virtue of pre-tensioning. These authors also state that in most coal mine roof types, the anchors start slipping from 30 to 70 kN.CABLE SUPPORT IN LONGWALL GATE ROADSthe opening, a factor that could improve roof support in thin-seam mines. Some consideration is also being given to using a single-pass system in gate roads, where the cable bolts will be used both as the primary support for development and second-ary support when the panel is mined.
