First geodetic surveys for DTMMO creation started as early as in 1992 and this original digital map could have been affected by residual mining effect in later years.
Residual mining effects and positional errors of the DTMMO could therefore have manifested within the last 18 years.
Position of the Pfivoz cadastral district is suitable for testing of residual mining effects that could negatively impact positional accuracy of DTMMO.
With respect to the theoretic considerations regarding mining effects on a surface points' general movement, we can anticipate that vertical component of movement will significantly prove in the size of coordinate deviations of tested identical points meeting the [u.
Impact of residual mining effects on accuracy of the original DTMMO from 1992--due to standard deviations' values and means of coordinate differences in X and Y axis and positional deviations--was not proved.
This is mainly the mining effect
- the baseline assumption is that we recover in the second quarter, that the mines sort of recover even with the rationing of electricity consumption.
The MPI claimed that, through assessments of a representative who visited the island late last year, Misima Mines Ltd (MML) and, therefore, parent company Placer Dome were avoiding responsibilities for significant mining effects
on ocean habitat and villagers' water supplies, as well as for the full inclusion of all legitimate stakeholders and claimants in the mine closure process.
The court ruled farm stands are an agricultural practice that must be taken into account when evaluating mining effects
The tanks are no solution for the aquatic lire that lived in the now-ruined springs, or the animals that drank from them, notes the Raymond Profitt Foundation, a Philadelphia-based nonprofit group that studies mining effects
And in the East, where most mining effects
are associated with coal, Don Barger, NPCA's Southeast regional director, notes that acid drainage from past coal mining is having an impact on such sites as New River Gorge National River in West Virginia and Big South Fork National River and Recreation Area in Tennessee.
