“…The UCS is considered as the most important mechanical property of rocks in geo-engineering and geotechnical works (Nazir et al 2013). This parameter is widely used in stability and instability analysis of surface structures and underground openings such as in mining operation, slope stability and tunnelling (Ojo and Olaleye 2002;Saedi et al 2018). The laboratory testing is the most reliable and indirect method of determining the UCS of rocks.…”

This paper deals with the analysis of effects of mechanical properties of rock on penetration rate and specific energy. Five specimens were collected from the four locations in Federal capital territory, Abuja. These samples were subjected to laboratory point load strength index using point load testing machine. Results of the point load tests were used to estimate the uniaxial compressive strength of the rocks. The penetration rate and specific energy were determined using empirical equations. The results from the investigation showed that the rate of penetration decreases with increase in rock strength and the specific energy increases with increase in rock strength. Based on the investigation, a number of linear relationships that described the effects of mechanical properties on penetration rate in the drilling process were obtained with strong correlation coefficients.
