印度冈瓦纳系煤层槽波探测技术的适应性

THE ADAPTATION OF SEISMIC WAVE TECHNIQUE FOR THE COAL SEAMS IN GONDWANA SYSTEM OF INDIA

摘要: 冈瓦纳系煤田占印度国家煤炭储量的99%。槽波探测技术是印度国家煤炭部第一次引进的矿井小构造物探成套技术。通过在A2、A3两个面的槽波探测工作,初步了解了其主采煤层的槽波条件、波速、频率和槽波穿透距离。

Abstract: The coal reserve of Gondwana coal fields in India accounts for 99% of that in this country.The seismic wave technique is the geophysical assembly one for detecting the minor mine structures introduced by the Indian Ministry of Coal Industry for the first time.Through the seismic wave exploration by us in A2 and A3 working faces,the conditions,velocity,frequency and penetrating distance of seismic wave in the main mining seams are understood preliminary.
