Abstract

As we know, the determination of rock strength by using the examination method, are time consuming and also money consuming. There for, in this research we are going to examine rock strength by using the new friction transfer method. This Method is called friction transfer, because friction making has the main role in power transfer. The examination is according to the following process. First we put a half core with 5 centimeters in diameter exactly at the place of examination. Then we put the friction transfer machine on the cylinder and we enter rotation power in it. Now we can determine the maximum power used for breaking the cylinder. Here we refer to the calibration and determine the strength by friction transfer and related machine, some other experiments have been done in concrete industry. The effect of cylinder depth is another instance that has been studied in this way. Experiments show that as cylinder depth increases form 12 millimeters to 64 millimeters, there would be direct effect. in this research we talked about rock friction strength and calibration curve description. We hope that could be successful in this industry.
