·The supporting effect of cone bolts has been studied by many researchers The concept of cone bolts was developed in South Africa [7] [8] and these bolts have reportedly been used in a few Australia mines [9] Tannant and Buss [10] conducted pullout testing of cone bolts for different grouting materials and found that the maximum axial
·In the early 1990s Professor Ortleep in South Africa proposed the concept of an energy absorbing support system Ortlepp and Stacey 1998 Ortlepp 1992 Ortlepp 1994 In 1990 Jager in South Africa developed the first real set of energy absorbing rock bolts cone rock bolts Jager 1992 This anchor consists mainly of a smooth metal rod

·the ratio of the member diameter to the bolt diameter Grosse and Mitchell 1988 perform a very detailed analysis of a single bolt joint also restricted to a particular geometry and note that the stiffness of the entire joint including bolt nut and member deflection is a strong nonlinear function of the ex ternally applied load
4 ·Developed by Canam Elocone nuts are special elongated nuts that can be used to correct problems encountered when the anchor rods are installed without enough projection above the concrete foundation These nuts are fabricated by machining a piece of high strength steel into two distinct forms In order to develop the tension capacity of an

In this paper a dynamic simulation model for a cone bolt is proposed based on an experimental study Drop weight tests were performed on resin based cone bolts These experiments revealed that the bolt has two energy absorption mechanisms sliding in the resin and plastic deformation
·For greased debonded bolts the cone plough varied from % to % with an average of % One non greased bolt and all three greased debonded bolts were dynamically loaded the third time Drop 3 Again the test results showed large variability in terms of cone plough behaviour For one greased bolt the cone was locked in place
It was found that local bonding between the bolt and the grout can prevent the cone from moving and effectively absorbing dynamic energy To solve the debonding issue and provide consistent performance of Modified Cone Bolts MCB we developed a new patented debonding agent in the form of a plastic sleeve installed over the shaft of the conebolt
·A full cone point depending on diameter and size of the bolt can be more labor intensive to produce Often a semi cone point is sufficient for the function of the bolt and often a cone point is unnecessary In fact semi cone point and cone point are relative terms that should be defined before a fastener can be produced Drift pins

·A cone nut is a fastener to secure bolts screws and other components It is also known as a cone shaped nut or a conical nut A cone nut has a wide base that tapers to a smaller diameter at the top forming a cone shape This unique shape allows the nut to be used in tight spaces where a traditional hexagonal nut cannot fit
