【摘要】：基于神東礦區(qū)大礦周邊小窯開采的特點,在綜合分析各種火源探測方法優(yōu)劣的基礎(chǔ)上,優(yōu)選出利用瞬時法測量氡氣可以滿足小窯隱蔽火源探測的要求。對石圪臺煤礦南部小窯進行隱蔽火源探測,利用中值法對測點氡值進行劃分,確定氡值異常值,結(jié)合氡值濃度表面圖和等值線圖劃分溫度異常區(qū)域。最后給出溫度異常區(qū)域的治理建議,利用地面鉆孔注漿或剝挖隔離火區(qū)治理小窯火區(qū),以保證礦井安全生產(chǎn)。
[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.
