Title: | 1975 Kia Ora GML 774E Mine Survey |
Title Holder / Company: | Not Given |
Report id: | CR1975-0170 |
Tenure: | GML774E |

Abstract: | A survey was carried out which related three surface stations to the workings underground at approx 60m level. Station Marking - On the surface, Stations A & B marked with long white survey pegs with aluminium tag designations whilst Station C is a steel peg, low in the ground. Underground twelve short pegs, with aluminium tag designations, were placed in the backs of drives. Instrument - A Wild Level and Tri-pod was used both for surface & underground readings. Calculations - THe surface plan was plotted directly from readings, apart from the position of Station C, which was obtained using the isosceles triangle ACPs. Surface & underground stations were tied in by dropping two plum bobs & relating all underground readings to them. The positions of Ps & Pn on the surface were fixed mainly from station C. Plotting - Both plans were plotted on a scale of 1:250. Drive outlines are approximated. |
