Abstract

The need for coal is increasing every year, so that coal exploration activities need to be done to maintain the availability of these materials. Exploration activities generally use the correlation of geological method (analysis) and direct measurement using the geophysical method. One of the geophysical methods used is the downhole seismic method, to determine the quality of coal hardness through several seismic parameters, namely variations in the value of the initial wave velocity (Vp & Vs) and the wave travel time (Tp & Ts). This study aims to estimate insitu coal density and avoid mining land clearing and environmental destruction that are misplaced. This exploration activity is carried out at 6 measurement points.
