m absulote hole depth

Explanation:
due to deviations from the vertical there is nearly always a difference between true vertical depth (TVD) and absulote hole depth. This COULD be an explanation, although to me "ahd" is known as the abbreviation for the 'azimuth of hole deviation' given in degrees.

The paper recently linked by Kim Metzger shows THD and AHD side by side (p. 17)

m AHD

Explanation:
I have found AHD as Australian Height Datum - does your text refer to Australia? Your abbreviation would then refer to 895 metres Australian Height Datum.
For example see: http://www.goldcoast.qld.gov.au/t_standard2.aspx?pid=4854
"The outcome of a flood search is the Designated Flood Level, which is reported in metres AHD (Australian Height Datum), the nationally adopted datum or standard to which all elevation for mapping is to be referred. "

Having read Coqueiro's answer I think I am on the wrong track with this one - so please ignore!
