Because of the ore or rock mechanical properties, geological structure, the environment of blasting area etc., an open pit’s bench blasting is restricted or infected in different terms, different places and different conditions.

New compositions of light fibrous concrete are developed, compared to the known structures they have improved physical and mechanical properties and a low cost.
In the system with H3PO4 these components give high strength and heat-resistant properties.

In general, pipe jacking technology can reduce the amount of excavation for the deeply-buried pipes in terms of economic factors, therefore, it is feasible, but it is more economical to take the laying and excavation for small depth of pipes.
· Lack of further research on the soil disturbance caused by shallow pipe jacking construction as well as the disturbed soil properties.
Pipe section joint is an important factor in the construction of pipe jacking.
The strength and size of the washer are major factors in the construction control.

Introduction The former Soviet union scholars C.C Vyalov etc. through the simulation tests of frozen sidewall found that: Because of permafrost has strong rheological properties, the frozen wall over time to develop the large creep deformation may also cause frozen tube fracture before the frozen wall damaged and lost the bearing capacity.
Frozen soil creep is always the forefront question in the mechanical issues, identifying the creep index and forecasting creep model of frozen soil are two large tasks in the creep test study.
During this period, the creep properties also got enough attention in the design of artificial frozen wall (Radd, 1978).
In the test, load and displacement and deformation, confining pressure and wave over time were acquainted and stored automatically, and these provided a reliable basis for the study of three-axis mechanical properties of artificially frozen soil samples.
From the typical relationship (Figure 2) between creep rate and time in different confining pressure and frozen temperatures we knew that: the strength of artificially frozen soil is one of main factors affected creep in different freezing temperatures.

And the extraction process is affected by many factors, such as thiocyanate concentration, oxidant concentration, liquid-solid ratio, temperature, and reaction time, especially pH and the category of oxidants, which can be chosen properly to make the method extensively applied in industrialization.
Introduction As we all known, precious metals are served as a main part in our all sorts of lives since ancient times, especially gold which is highly valued for its special physicochemical properties.
And as is known to all, just as the table 1 shown, the extraction process is affected by many factors, such as thiocyanate concentration, oxidant concentration and category, liquid-solid ratio, temperature, reaction time and pH [7-8,21-25].
Among them, thiocyanate concentration and oxidant concentration are the main influence factor through orthogonal experiment.
However, slightly affect was presented for the reaction temperature and thiocyanate concentration.

Temperature Influence on the Viscoelastic Electromechanical Deformation of Dielectric Elastomer Jun-Jie SHENG1, a, Yu-Qing ZHANG1, b, Shu-Yong LI1, c, Hua-Ling CHEN2,d 1Institute of Systems Engineering, China Academy of Engineering Physics, Mianyang 621900, People’s Republic of China 2School of Mechanical Engineering, State Key Laboratory for Strength and Vibration of Mechanical Structures, Xi’an Jiaotong University, Xi’an 710049, People’s Republic of China ascu2005sjj@163.com, b412zhangyq@caep.cn, c412lisy@caep.cn, dhlchen@mail.xjtu.edu.cn Keywords: Dielectric Elastomer, Temperature, Viscoelasticity, Electromechanical.
Temperature can significantly affect the performance of a viscoelastic dielectric elastomer (DE).
DE exhibits time-dependent property and the deformation of DE is also highly relying on the rates of activation [7,8].
Recently, the influence of both temperature and deformation on dielectric constant is considered during the establishment of free energy function of DEs [19,20], but does not involve any viscoelasticity and no attempt has been made to describe how temperature affects the viscoelastic processes.
As the Maxwell stress drives the DE system substantially, thus the amplitude increases at the same time with the increase of the actuation factor at high temperature for the viscoelastic electromechanical performance of DE.

Well underground coal gasification is a complex technological process with considerable environmental effect being stipulated by the abovementioned factors.
Thickness of a coal seam, its elementary and qualitative composition, physical and mechanical properties, depth of occurrence, texture, structure and elementary composition of the rocks enclosing the seam, water influx, disjunctive and plicative faults etc. are basic criteria while evaluating coal seam suitability for UCG.
Coal seam is gasified under natural conditions; thus, filtration properties of seams play a major role.
Those factors are taken into consideration along with the evaluation of general water influx from the coal seam and enclosing rock mass into a gas generator.
Deformation properties of sedimentary rocks in the process of underground coal gasification.

Static electricity makes original regular warps disorder and adjacent yarns wind each other in weaving process，these bring weaving difficulty and affect the quality of the product，moreover, static electricity has potential security risks if electrostatic phenomenon is serious.
（1）Using high hygroscopic fibers Using natural or synthetic fibers with high hygroscopicity to produce pure textiles，such as cotton，wool，viscose fiber，etc，In order to improve hygroscopicity of textiles and reduce the adverse effects of electrostatic phenomena，enterprise can use natural or synthetic fibers with high hygroscopicity to blend or interweave with chemical fibers with poor hygroscopicity，such as polyester，polyamide fiber，acrylic，etc.But this method is greatly influenced by environmental factors，in the low humidity of the air environment，the antistatic effect is not obvious，even will enhance the electrostatic phenomena
The mechanism of antistatic agent has two main types，①antistatic agent can form continuous conductive film after covering and improve the conductive performance.②the good hygroscopicity and directional property are the main factors that influence the antistatic effects of surfactants，hygroscopicity is not dominant role.
There are generally two kinds of methods to manufacture antistatic fibers，①The hydrophilic polar groups are implanted into high polymer for fiber forming through certain methods，such as blending，copolymerization，graft modification，etc；②Durable antistatic fibers are obtained by adding internal antistatic agents to spinning solution. 2.2 Conductive fibers The conductive fibers for textiles have following features：have appropriate fineness，length, intensity；have good flexibility and cohesion，easily blend of interweave with other fibers；have friction resistance，flexion resistance，antioxidant resistance，corrosion resistance and can resist certain mechanical action；do not affect handle and appearance of textiles；have good electrical conductivity and durability.
Metallic series have many advantages，such as good conductivity, good heat resistance，good chemical resistance，but they have some drawbacks too，for example weak cohesive force，poor spinning property，expensive，etc

One of the factors that affect the accuracy of positioning of industrial robots is their design concept (kinematic structure).
Other factors limiting the wider application of robotic machining are complexity programming and unsatisfactory stiffness.
When designing robotic workstations for handling of material, material properties are the most important factor.
The reasons of this are mainly two factors.
The problem in measuring of an angle of ascent occurs when adding additional accelerations, except gravitational acceleration, affecting an accelerometer.
