The basic characteristics of the collapse is described clearly according to the geological exploration data, and the stability of the dangerous rock mass and the collapse accumulated body is analyzed in the way of engineering geology and stereographic projection.
Engineering geological analysis[4].
Judging from the engineering geological analysis and stereographic projection analysis, the synthesized stability of W1 dangerous rock is an unstable slope structure, and the whole degree of stability of the dangerous rock mass is less stable, dumping and fall off the block are the possible failure modes and the collapse direction ranges from 260 to 270.

The Japanese will select moderate heat Portland cement (P•MH) and low heat Portland cement (P•LH) according to the weather conditions, not only use in mass concrete engineering but also use in non-mass concrete engineering.
In China, there were some nuclear power projects and irrigation works which have large were using P•MH and P•LH, but P•MH and P•LH were still not generalize in civil engineering.

Introduction Gradually, the non-electric initiation system has been more used and been the main method in our country blasting engineering.
For example, in 1998, misfire appeared in Zhangzhou stone a flat chamber blasting engineering.
So, it should have to study methods of control and detection on firing circuit, which can improve the safety property of blasting engineering.
