利用MH—2煤层厚度探测仪探顶煤厚度

Detecting the thickness of top coal with Type MH 2 coal seam thickness detector

根据顶煤厚探测条件， 提出对 Ｍ Ｈ—２ 煤层厚度探测仪进行改进， 采用自激自收的声波反射方法来探测残余顶煤厚度，通过反复试验改进激发接收的声波反射方法及激发接收装置，并开发出自动解析软件， 取得了良好的应用效果。

According the conditions for detecting the thickness of top coal,the improvement for Type MH—2 coal—seam thickness detector was developed which adopted the principle of sound wave reflection with self stimulating and self receiving to detect the thickness of rest top coal.The stimulating set and receiving set both were improved passed through repeated tests and a set of automatic analytic software was developed.A perfect practical result was acquired.
