Risk assessment is too geared towards single-incident and physical abuse," she said, which ignores the harm controlling behaviour can do over a long period of time.
On the basis of summarizing and analyzing previous heat-harm control technologies, and aiming at the usage of deep geo-thermal energy, HEMS-technology has been successfully developed.
This paper, aiming at deep mine heat-harm control and utilization of thermal heat, introduced the development and field test of HEMS, getting conclusions as following: (1) By the analysis of current situation of mines in eastern China, summarize the main problems faced in deep mines, the heat-harm control, energy waste and environmental pollution problems by ground coal-firing boiler.
By the analysis of current situation of mines in eastern China, summarize the main problems faced in deep mines, the heat-harm control, energy waste and environmental pollution problems by ground coal-firing boiler.
Finally, we find that the high temperature exchange machinery system (HEMS) technology that use mine discharge as the cold source, is excellent to heat-harm control in deep mines.
Results of this project illustrate that it is efficient in heat-harm control with the temperature decrease of the workplace down to 26 29 °C, and being 4 6 °C lower than the original, and the relative humidity 5 %–15 % lower than before.
The system combines cooling, using underground mine water drainage, and utilization of heat-harm as geo-thermal energy, achieves the purpose of underground heat-harm control and the ground coal-firing boiler heating replacement, forming a green circular production system with cooling underground and heating on the ground (He et al. 2006b).
All these make it difficult to spread for heat-harm controlling in deep mines.
"Recently completed testing and data analysis show that E15 does not harm emissions control equipment in newer cars and light trucks," she said in a statement.
Rashid, who last played for England in 2009, did his chances of a Test debut in Antigua on 13 April no harm with control and variation on a pitch that offered turn.
