Mining activities are carried out in a place where a deposit of the excavation is declared economical. In other words, mining activities cannot choose / determine the location of activities that can avoid the potential impact of its activities to the surrounding environment. In harans that are hard, often mining activities will use explosives to be able to carry out crumpled rock (overburden) which cannot be done directly by the digging tool (other than also for economic reasons). The use of explosives will result in vibration that potentially impact into the surrounding environment. The sacred site of Goa Dalem in the mining business permit area is included in the area that is vulnerable to this affected. Therefore, it is deemed necessary to observe the long-term movement of the dalem cave rock block to be able to know the actual conditions for the potential impact of the existing vibration.

(2) Data acquisition and engine to calculate the movement of the cave rock block. (3) The analysis regarding the possibility of movement aims to determine the indication there is or whether or not the movement on the cave-cave rock block with the statistical method. Recommendations related to technical steps need to be done either or not indication of the movement on the cave-cave rock block.
