在研究水体下采煤技术中,遇到了江、河水面宽在250米以上,利用钻孔冲洗液法无法观测冒裂带高度的困难。这个问题不迅速突破,势必成为水体下采煤技术在观测手段方面的一大障碍。七十年代兴起的弹性波跨孔穿透技术的应用给人们以新的启示。用弹性波跨孔穿透技术所获得的冒裂带范围内的大量的波速资料、使解决这一问题成为可能。本文旨在对用弹性波研究冒裂带高度问题进行理论探讨。
In the study of coal mining technology, met the river, river width of 250 meters wide, the use of drilling fluid method can not observe the height of the fissure zone difficulties. This problem is not promptly broken, is bound to become a major obstacle in the observation means of coal mining technology under water. The rise of the seventies elastic wave cross-hole penetration technology to give people a new inspiration. The use of a large amount of velocity data in the region of the fissure zone obtained by the elastic-wave cross-penetration technique makes it possible to solve this problem. The purpose of this paper is to study the problem of using the elastic wave to study the height of the fissured zone.
