α探测技术及其在煤矿地质中的作用

DISCUSSION ON THE ALPHA DETECTING TECHNIQUE AND ITS APPLICATION IN COALMINE GEOLOGY

论述了α探测技术的实质及其应用基础。利用该技术不仅可在煤矿井下快速查找隐伏构造等,而且可在地面用于探测隐伏断层、圈定隐伏陷落柱的范围。试验结果证明:α探测技术是一种快速、灵活、经济的放射性物探手段,可在煤矿地质中发挥重要作用。但因仪器等原因,在实际应用中有其局限性。

The crux and application foundation of alpha detecting technique are discussed in this paper. By using this technique, hidden structures can be quickly detected in underground, and the position of hidden faults and the range of hidden sink-hole can be detected on surface too. The test results have proved that this technique is a quick, flexible and economical radioactivity geophysical prospecting tool, it can be playing a more role in coalmine geology. But because of the instrument, etc. , this technique has some limitations in its application.
