To solve the problem of image faintness in the terrane monitoring system in coal mine underground, a solution using wavelet transform to enhance images is propo sed. Having analyzed a traditional way of image enhancing in wavelet transform o n the basis of Mallat, this paper presents an arithmetic, which uses threshold- value mean on the basis of wavelet transform and magnifying coefficient utility arithmetic, to fulfill the enhancement of image with noises. As an example, the novel arithmetic was applied to the image-enhancing processing of an anchor-ho l d drill in coal mine. The results show that the proposed solution can effectivel y enhance terrane image of the anchor-hold drill in coal mine and get a better vision effect..
