China University of Mining & Technology (Beijing) School of Mechanics and Civil Engineering，Beijing 100083；) Keywords: deep;Geotechnical mineral;soft rock types;deformation mechanical mechanism Abstract: As soft rock roadway projects have the characteristics of large deformation, and earth pressure,difficult to support, and all that make shallow form of support can not meet the needs of the soft rock roadway, the main reason is that the soft rock roadway has compound deformation mechanism, which makes that the single support physical science features and rock mechanical properties can not be coupled, and a key part of the soft rock roadway begins to undermine firstly, which leads to the instability of the entire supportive system.
This paper utilized the deep soft rock roadway of Daqiang Coal Mine of Tiefa Coal Industry as engineering background, systematically studied the mechanical characteristics of the soft rock roadway engineering geology, deeply analyzed the mineral properties of surrounding rock, and proposed the soft rock roadway’s compound deformation mechanism and conversion process of transforming compound into single deformation mechanism, providing important theoretical basis for designing .Daqiang Coal Mine deep soft rock roadway Introduction The Tiefa Coal Industry (Group) Co., Ltd.
The temperature below-750m is high, the design only through mining, processing, environmental protection and other technical means to address the impact of unfavorable factors, to take full advantage of the favorable factors, playing equipment performance to ensure that mine production scale. 2.2 Ida geological structure The Ida coal-bearing stratum is flat and dip 5～15°,we look at the whole region, trending east-west, south dipping monoclinal structure.
Although the level tectonic stress value is not great, but for the most Daqiang Coal Mine soft rock roadway, horizontal tectonic stress is one of the main factors of the roadway destruction and even bottom heave.
At the same time, the surrounding rock is influenced by tectonic stress, especially when the level tectonic stress is one of the main controlling factors of the roadway damage and floor heave.

The top five about peaks describes the extremes of micro-EDM surface roughness, and is strongly affected by stochastic factors.
The top five about valleys describes the extremes of micro-EDM surface roughness, and is strongly affected by stochastic factors.
Summary From the above research, it’s found that among the given parameters, the arithmetic mean deviation and the root mean square deviation about peaks and valleys belong to amplitude parameters, which are the most important characteristics of surface topography; while the root mean square slope about peaks and valleys belong to comprehensive parameters, which are the main factors to influence surface friction properties, also have great sensitivity to surface scales, but their values are very dependent on the measurement resolution.
Additionally, the bearing ratio about peaks and the fluid retention capacity curve belong to functional parameters, which could reflect some special properties information.
Thus, further research about the characterization of micro-EDM surface roughness parameters still needed to be studied, and its emphasis should be put on the surface characteristics and the surface properties.

Computer Numerical simulation and simulation results show that the regenerative brake control parameters for hybrid vehicle fuel consumption and greater impact on the SOC, and the regenerative braking may affect the minimum speed limit of the regenerative braking effect, the lower the minimum speed limit the greater the braking energy recovery, thesis research is regenerative braking hybrid vehicle control parameters selected to provide a reference.
Sugawara developed an emission-optimized track assignment model that used average speed CO emission factors developed by the California Air Resources Board.
Influence Analysis The dynamic property of the hybrid electric vehicle is not affected by the regenerative braking control parameters.
In the event of larger participation extent of the regenerative braking, the power generation torque of the motor will be greater, the batteries will have more in-depth charging opportunities, SOC will maintain good level, and the loss of mechanical braking power will be less, thus, the fuel consumption will be superior in case of higher regenerative braking proportion compared to that of the lower regenerative braking proportion.

Because the metallic hafnium has good combination properties, that makes it the preferred material for control rods of nuclear reactors.
Compared with external factors, the shape and geometry size decide the impact resistance crack value to a great extent.
The mechanical property of stainless steel is little affected by neutron irradiation, therefore, the impact resistance of the control rod assembly enhances obviously.
From the above data, the mechanical property of hafnium plates excels the ASTM standard requirements.
