Test process drilling for gold is an important step in the every prospecting and gold mining industry. Test drilling is a step that is used continuously to obtain samples of bedrock in the land of gold mining project. The sample is then tested to determine whether it is gold in the project area in mining and to estimate the amount of gold that can be mined in the area.
Before test drilling for gold, there are several steps that can be done early, it is made to prospecting works. Often the area to test can bushes, hard terrain or other obstacles drilled, which may influence the outcome of exploratory drilling. It is important, therefore, it will be handled first.
One step that can be used is by ridding the area which will be conducted test drilling. This can help reduce the amount of land the ground which will done testing on drilling,thus support and make to be effective the test holes are drilled.
In the process of test drilling in gold mining is intended to determine whether the area has gold potential which can be used for large-scale mining.This is very helpful in determining the amount of gold deposits
and grade gold contained in the soil in the area that will be in mine.
Test drilling can also specify the information that is significant of the general geology of the rock structures that exist in the soil at the prospect area, the geochemical structure and other information from other minerals besides gold deposits existing in the test drilling area
For most in scale test drilling in mining area is often gridded out into small grids that can determine the number of holes to be drilled. Sometimes in the drilling process is done in a manner soil formation such as rifts, ditches, river basins or even valleys.
If in the process the first step is successful, then to get a drilling method that is more accurate in determining the mineral content of gold or may be in the process of the most extensive can be implemented
Some of the methods most commonly used test holes, you can use includes hand drilling, rotary drilling, percussion drilling and diamond drilling.
The significance of the test drilling for gold
test drilling is to enhance the importance of prospecting before a mining operation, and drill testing is one of the methods most commonly used for sampling.
Albeit with very expensive, it takes some of the risk and guesswork out of the mining process and an estimate of how much gold there is in the area
The type of drilling specifies the device to be used.
This is carried out in at a little place for little operations. Hand drilling done by using a manual hand, the phase required prior training stage, as sample tubes and augers. These drills can not penetrate bedrock and thus limited in its application entirely.
Variety of hand drilling tools can be used for hand drilling, but hand test can only for little gold mining drilling.The advantage of the hard drilling reduced cost of major methods, and this may be the best method for individual miners who lack the resources for greater exploration.
This type test drilling where the drilling equipment can be used to enter into the bedrock up to a depth of approximately 10 meters. Percussion drilling is drilling that uses compressed air drilling equipment, this makes lebihh far stronger than using a hand drill.There is also drilling using large air drilling equipment ,which can be used in complex drilling in the mining area.
Rotary drilling is drilling relatively expensive yet very easy to use in a variety of conditions. In the drilling process using a ring and an air compressor in the process of drilling holes to be tested. With the true tools and skilled workers, this type of exploratory drilling takes the least time of all available drills. The drill may obtain samples from between 20 and 100 foot holes.
This is the most versatile drill testing method that can use. The machines used for this type of drilling gets superior most samples since it can drill deep and at a certain angle and conditions.
In most cases, drills are used herein, can be powered by electric engines, gasoline, diesel, and even air. However, the process can only slow and very expensive in practice and thus it is used only for complex projects that require extensive drilling.
