ABSTRACT Kutai Basin which located in Eastern Kalimantan stored a lot of abundant natural resources such as: coal deposit which has big potential to be one of energy resources. In coal mining process, estimation of mineable deposit can be estimate by calculation and analyst base on detailed exploration which is drilling and mapping, calculation of coal deposit conducted in order to determine how much of coal deposit can be mined based on stripping ratio, this information will help to make a fine decision for the economic reason In a mine exploration, in drilling process there is called borehole deviation, borehole deviation is a deviation dip of the borehole from the target dip. Conducting a survey on the dip of a borehole will contribute important parameter data to improve the accuracy of the calculation of reserves, the accuration to estimate coal reserve will improve. Digital electronic sensor Gyroscope, Accelerometer and heading sensors (digital compass) can help to get the value of the dip and azimuth in a borehole
