Contain Information About :
Diamond drilling, What are the reasonable drilling meters? How long should the holes be? What is the right direction to drill? What is the most suitable angle? Where are the best places for core drilling? You get continue sample for color and texture analyses from certain depth. You can measure fractures and other discontinues and you are able with some accuracy to calculate and visualize their position in bedrock. Drilling is expensive compared to geological mapping or geo-radar research. It is difficult (or some way unreliable) to determine manually the direction and angle of stone structures and fractures from rotated drill cores. Light diamond core and percussion drilling machine Geo Machine 100. Natural stone deposit is a volume of bedrock with uniform color and texture appearance and far apart fractures. Drilling in Granite : Formations are many times larger than deposit area. Deposit areas (10-30 hectares) have usually 2-3 color – texture types. Deposit borders are topographic or deposit is located in certain color – texture zone. Formations are larger than deposit area. Drilling in Diabase stone : Formations are smaller than optimal deposit or quarry area. Deposit and quarry areas (1-2 hectares) have both contact and topographic borders. Topography Deposit areas, which are 20-30 m high with natural 3-5 m benches, are easier and cheaper to quarry than flat surfaces (Figures 2a and 2b). Flat bedrock surfaces are typical in southern parts of Northern Ostrobothnia area in Finland. Pyroxene granite: Raatokorpi, in municipality of Rantsila (PNASTINA project in the year 2004). What are the reasonable drilling meters? Exploration stage, Inventory stage. It is much more easier to get an impression about fracture system and make drawing, if drilling is done against main vertical fracture directions than to any other (diagonal) direction.
