Abstract - For evaluating the rock material for different
purposes, the physio-mechanical properties of materials are the most important and key parameters. In this present study the rock material were collected from a mining quarry located in India and laboratory investigation was carried out for observing the behavior of rock under different tests namely point load test, Uniaxial compressive test and Tensile test. Key Words: Physio-mechanical properties, Point load test, Uniaxial compressive test, Tensile test.
1. INTRODUCTION Mineral is a naturally occurring inorganic and homogenous mixture which having definite physical and chemical composition, which are found in earth crust. The combination of one or more minerals will from a rock. The physical and mechanical properties of rocks play a major role in performance of rocks under various jobs and these properties will helps in classifying them [1]. The properties of rocks will give the information about the performance of rock under different conditions. Hence the knowledge of the properties of rock is very important for utilizing it for particular work [2]. In mining industry many accidents happen due to not having the lack of knowledge in the properties of rocks [3]. The rock strength is the one of the important mechanical properties of rock and it can be calculated by means of various laboratory investigation [6]. In this paper a laboratory investigation is carried out for finding the some of the properties namely point load test, Uniaxial compressive test and Tensile test.

Methodology For observing the behavior of rock under different tests the rock samples are collected from various places in Andhra Pradesh, India. As the field collected samples are not in the perfect size and shape, the core specimen is drawn from the field collected sample with the help of core cutting machine which is shown in Figure 1. Sample preparation is the first step that need to be done in the rock testing process this helps to obtain the good results during the investigation in the lab. The prepared test samples are shown in the Figure 2
