长距离采煤工作面高压喷雾降温实验研究及应用
Experimental research and application of high pressure spray cooling in long distance coal mining face
摘要
Abstract
For the problem of high temperature heat damage at 1012102 working face in Yuanzigou Mine,the best spray pressure and nozzle atomization parameters are determined by using the method of spray cooling experiment.The numerical simulation meth-od is used to simulate and analyze the influence of different spray temperature and spray spacing conditions on the cooling effect,and the comfort of human body before and after spray is used to analyze by the linear regression method.The results show that:when the spraying system in the synthesized mining face adopts the group spacing of 10 m,the water temperature is 286 K,and the pres-sure is 6 MPa,the single group peak temperature reaches 1.3℃compared with the conventional ventilation method.After the applic-ation in the field,the temperature of most areas on the sidewalk side of the working face was lower than 26℃,the maximum temper-ature dropped to below 27℃,the minimum temperature was as low as 24.7℃,which effectively realized the regional cool.关键词
