The invention provides a method for testing surrounding rock integrity, comprising the following steps: selecting a suitable test hole in a test area, arranging an auxiliary hole near the test hole, arranging a monitoring hole in the auxiliary hole, and arranging a monitoring instrument in the monitoring hole; arranging two inflatable expansion rubber gaskets in the test hole, inflating the inflatable expansion rubber gaskets when the test is started to ensure that the inflatable expansion rubber gaskets are sealed with the surrounding rock to form a sealed test section in the test hole, wherein the sealing strength is higher than the inflating pressure of the test section; and inflating the space of the test section by inflation equipment, wherein the inflation pressure is higher than thecracking strength of the surrounding rock. The method overcomes the limitation of the rock scale by the indoor test method, and avoids the secondary disturbance of the surrounding rock in a coring process. Meanwhile, compared with the traditional pressurized water test and the on-site rock mechanics test, the test method is small in disturbance of surrounding rock on the site with no need of complex and cumbersome instruments, and can more intuitively reflect changes in the integrity of the surrounding rock.
