SURFACE GEOPHYSICAL METHODS FOR DETECTION OF .

fers the possibility to define subsurface structure beyond the ability of other methods. Seismic reflection has been applied to mapping the continuity of coal seams in advance of longwall mining, especially in Europe where mining is commonly at depths greater than 1000 feet and it is difficult and expensive to characterize a coal seam with borings.

underground coal mining as it can create a serious threat to mining safety and productivity due to its explosion risk. One of the most important duties of ventilation in underground coal mines is to keep methane levels well below the explosive limit by diluting methane emissions that occur during mining.

Lithologging – Borehole Cores and Sampling techniques .

Lithologging of drill core of boreholes is an important stage in mineral exploration and it is done in reconnoitery, exploratory and evaluation stages of drilling to characterise the lithology. What is lithologing? Lithologging is systematic, depth wise enumeration of details of Core/Sludge samples or rock exposure in cross sections. Objective of lithologging: The basic objective [.]

Solution Mining - Karnalyte Resources

Mar 23, 2020 · Conventional underground mining methods are predominantly used for Sylvinite potash mines throughout the world. The mineral Carnallite is deliquescent, with the ore absorbing moisture from the atmosphere. This tends to weaken the structural strength of the ore body, and renders it unsuitable for conventional mining.

Application of Well Logging Techniques for Identification .

Correlation of well logs is an important step in geophysical and geological interpretation, to develop geologic models and time – depth conversion. Well log correlation is the process of determining corresponding depths among the boreholes. Figure 8 has shown the borehole to borehole (BH No -53, 45& 46) coal seam correlation and

Ore Reserve Estimation Method

Estimates of the tonnage and average grade of ore deposits (ore-reserve estimates) are made for various purposes. They may be made by examining engineers as a basis for placing a value on a mining property in connection with reports on behalf of owners or vendors, on the one hand, or for prospective purchasers or lessees, on the other.

Application of Advanced Geophysical Logging Methods in the .

Borehole-deviation logging records the three-dimensional geometry of a borehole (Keys, 1990). Knowledge of borehole deviation is important to determine the true location and orientation of features intersected by the borehole. Borehole deviation tools generally indicate borehole inclination to within +/- 0.5° and direction to within +/- 2°.
