【摘要】：基于神东矿区大矿周边小窑开采的特点,在综合分析各种火源探测方法优劣的基础上,优选出利用瞬时法测量氡气可以满足小窑隐蔽火源探测的要求。对石圪台煤矿南部小窑进行隐蔽火源探测,利用中值法对测点氡值进行划分,确定氡值异常值,结合氡值浓度表面图和等值线图划分温度异常区域。最后给出温度异常区域的治理建议,利用地面钻孔注浆或剥挖隔离火区治理小窑火区,以保证矿井安全生产。
[Abstract]:Based on the characteristics of small kiln mining around large mines in Shendong mining area and on the basis of comprehensive analysis of the advantages and disadvantages of various fire source detection methods, it is found that the instantaneous method can be used to measure radon gas to meet the requirements of small kiln hidden fire source detection. The hidden fire source of the small kiln in the south of Shigetai coal mine is detected. The radon value of the measuring point is divided by the median method, the abnormal value of radon value is determined, and the abnormal temperature area is divided by the surface map of radon concentration and the isoline map. Finally, the paper gives some suggestions for the treatment of abnormal temperature area, and uses the ground borehole grouting or peeling to separate the fire area to control the small kiln fire area, so as to ensure the safe production of the mine.
