瞬时法测量氡气在小窑隐蔽火源探测中的应用
Application of Instantaneous Measurement of Radon in the Detection of Hidden Fire Sources in Small Coal Pits
-
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: Instantaneous measurement of radon was preferred in view of exploitation characteristics of small coal pits around the big coal mines in Shendong Mining Area and comprehensive analysis of advantages and disadvantages of various fire detection methods. The hidden fire sources of small coal pits in the south of Shigetai Coal Mine was detected. The radon value was divided using the mid-value clustering. The abnomal value of radon was determined. The abnomal area of temperature was divided by combination of radon concentration surface and contour map. In order to ensure the safe production of coal mine, the governance proposals by using the ground drilling grouting or excavation isolation fire area are given finally.
