Abstract: The extraction of deep coal resources is challenged with the problems of high ground stress and strong disturbance.The key to solve the problem is to study the effect of rock rheological disturbance.In order to further study the rock rheological disturbance effect, according to the experimental requirements, aiming at the short-comings of the previous test system, a RRTS-IV rock rheological disturbance effect Test system has been developed.The test system mainly includes four parts:the main engine of the tester, the disturbance loading device, the step by step loading auxiliary device and the test and analysis system.The main engine of the tester applies the lever principle, and the two-stage lever is used to expand the force, and the expansion ratio is 1∶100, which can provide a long-term and stable axial pressure for the test.The disturbance loading device adopts the combination design of spring and stroke switch, which reduces the random reciprocating shock time of impact weight and makes the test data more accurate.The step by step loading auxiliary device applies the combination design of fixed pulley and bucket, and helps the tester realizes the function of low grade continuous and slow step by step loading, which provides the necessary conditions for the smooth progress of the test.The test analysis system is composed of a dynamic test signal analysis system and various types of sensors, which can dynamically monitor the stress, strain and impact disturbance.The performance of RRTS-IV test system is verified by the uniaxial flow test of rock and its disturbance effect test.The results of the test show that the experimental results obtained by the RRTS-IV type test system are consistent with the previous theories and research results, and the performance of the testing system is better than the previous testing system.The RRTS-IV test system is suitable for the experimental study of rock rheology and its disturbance effect.
