乌东煤矿＋600 m水平南、北掘进巷位于原曙光村煤矿老旧采空区下方，所形成的老旧采空区由于历史地质资料的缺失具有无规则性和隐蔽性，对目前安全回采造成极大的隐患.针对这一问题，确定采用 SIR－20地质雷达对老旧采空区的空间正分布进行探测以明确地质异常结构特征.探测结果表明在走向2800~2850 m、距巷道上方约2.5~3.5 m范围内的煤层含水量丰富，在走向2680~2650 m、距巷道上方1.4~1.7 m范围内为老旧采空区，煤岩体破碎严重，裂隙发育明显.
烏東煤礦＋600 m水平南、北掘進巷位于原曙光村煤礦老舊採空區下方，所形成的老舊採空區由于歷史地質資料的缺失具有無規則性和隱蔽性，對目前安全迴採造成極大的隱患.針對這一問題，確定採用 SIR－20地質雷達對老舊採空區的空間正分佈進行探測以明確地質異常結構特徵.探測結果錶明在走嚮2800~2850 m、距巷道上方約2.5~3.5 m範圍內的煤層含水量豐富，在走嚮2680~2650 m、距巷道上方1.4~1.7 m範圍內為老舊採空區，煤巖體破碎嚴重，裂隙髮育明顯.

The southern and northern tunneling roadway on +600m level in Wudong Mine is located below the old goaf in former Shuguangcun Coal Mine,which is the hidden trouble for cur-rent safety mining.Aiming at this problem,the SIR-20 GPR is adopted to detect the positive spatial distribution of the old goaf to clear the features of geological anomaly structure.Survey re-sults show that the coal seam has high moisture,which ranges between 2800 m~2850m on the strike and 2.5 m~3.5 m above the roadway;the coal seam fractures develop with rich water in rock body in the scope of 2680~2650 m on the strike and 1.1 m~1.7 m above the roadway;It's the old goaf in the scope of 2680~2650 m on the strike and 1.4~1.7m above the roadway where serious rupture and obvious fractures developing exist in the coal seam.
