These conclusions can provide references for the research and anti-vibration design of transmission line engineering.
Nevertheless, these still can't meet the growing requirement for the anti-vibration design of the transmission line engineering.
Therefore, it is necessary to study them deeply to meet the requirement of the engineering design.
Some conclusions have been drawn by means of the investigations and they can provide references for the research and anti-vibration design of transmission line engineering.

Application of Safety Appraisement of Blasting Operation in Coal Face of Blasting Mining Xinsheng Wang1, a, Tao Rong2,b 1 School of Civil Engineering, Henan Polytechnic University, Jiaozuo, Henan 454000, China 2 Personnel Division, Henan Polytechnic University, Jiaozuo, Henan 454000, China awxs@hpu.edu.cn, bRongt@hpu.edu.cn Keywords: coal face of blasting mining; blasting operation; safety technology; management measures Abstract: The coal face of blasting mine in underground coal mine is a very complicated system of disaster environment, the spatio temporal limit increases the accident probability of blasting operations.
So the safety appraisement method of safety engineering was applied.
To each kind of construction operation environment with serious injury potential, such as coal face of blasting mining, we all may carry out safety evaluation by adopting safety evaluation method in the field of safety engineering, thus discovered promptly the insufficiency on the safety management and the technical aspects, so as to take the effective measure to guarantee that the operational security.

Risk evaluation of environmental monitoring indexes for deep excavation Jiao Zhang School of Civil Engineering and Transportation, Shanghai Technical College of Urban Management, Shanghai 200432, China ggglg@163.com Key words: Deep Excavation, Risk Evaluation, Environmental Monitoring, Alarming Value Abstract.
The engineering alarming values of environmental monitoring indexes are generally ascertained according to the experiences or estimated values.
Once the detected data over the engineering values, the project will be alarmed, and some corresponding controlling measurements will be taken in time.
The risk alarming values of environmental monitoring indexes need to consider more factors than the engineering alarming values.
The risk alarming values and the engineering alarming values can be correlated by a risk modification coefficient R.

Therefore, based on rock mechanics experiment, it is necessary to further consider influence of plastic deformation mechanism to the stability of the borehole. 1 Introduction In recent 20 years, the couple phenomenon and problem has become important and height attention by engineer and dynamicist.
