Last Year's Dig

Last year just before we stopped the operation before the rainy days recess, we have sorted out that due to the increased volume of water, what we have reached may be covered with sand silt and erosion once more.

So to minimize the erosion and bar down, we have decided to install bamboo retaining fences to minimize the volume of sand back into our dig.
















Our dig was then approx. 44 ft MOL from the surface and the target concrete slab was then approch. within reach - meaning within 8- 10 ft. But then, the dewatering operation lasted for more than five hours per days which had been a burden to the operational cost and budget. So we have decided to call it off for theseason and be back on the next TH Season.


Directly on the bottom of the dig were to logs arranged west to east. meaning with the bigger diamter running from the west end to the east direction.
























We have to by-passed the said log and proceed downward as instructed by the people who have previously reached the concrete slab but were not give the oppurtunity to break it.

They described to us that the concrete slab was like a white marble with an engraved buddha figure on the upper right corner meaning with its top on the northeast corner of the slab. The "marble slab" according to them was so hard to break that the sledge hammer that they were using just bounced off to the surface of the slab. They were not able to break the slab.

I hope that this is our chance to prove that we are deserving to break and open up the concrete slab.

hi . this is marlon(alias)..we have tried to break hard cements such as this...try applying heat...like burning charcoal on top of it..then after all charcoal burned..apply water making the burned cement brittle...and repeat process until you break through..

maybe a sack of charcoal per process..in our experience we burned 3 sacks for a 3 feet deep concrete
