The invention discloses a charging method for improving peripheral weak surrounding rock blasting stability. The method comprises the steps that each shot hole is filled with an explosive tube, then filled with a water glass bag and finally filled with an alums bag to form a first charging cycle, a second charging cycle can be formed based on the first charging cycle, and therefore multiple charging cycles can be formed. After all the charging cycles are completed, the shot holes are plugged by stemming, water glass and alums produce a mixture under the influences of explosive shock wave during blasting, some mixture is shocked to the weak surrounding rock peripheral face, the gaps of the peripheral weak surrounding rock is filled with the mixture, the mixture is solidified within a short time and has the certain strength after being solidified, in other words, the peripheral weak surrounding rock is sprayed with a layer of reinforcing materials, and therefore the peripheral weak surrounding rock blasting stability is improved.
