Welwyn Hatfield Borough Council (The Council) have received funding to investigate and remediate an historical chalk mine located around Chantry Lane and Vigors Croft in Hatfield.
The Council has now completed the investigation works and is seeking a qualified and experienced contractor to undertake the remediation works.
The key findings of the design phase ground investigation have generally confirmed:
— The intrusive ground investigation has identified a network of interconnected mine
workings extending from at least four now infilled mine shafts located in the southeast
corner of Chantry Lane Copse;
— The general lateral extent of the mine is similar although the recent investigation has
indicated that the mine doesn’t appear to extend to the east of Vigors Croft road and to
the northeast while to the south of Chantry Lane the mine seems to be more extensive;
— The Feasibility Study Report assumed that the mine workings extend to depths of
between about 12 m and 18 m whereas the recent ground investigation has indicated
that the mine extends to depths of between about 7 m and 18.6 m;
— The condition of the mine is similar; the main difference being that the investigation
suggests that more of the mine is either partially or fully collapsed or in parts infilled with
backfill material;
— The ground investigation has provided further evidence of void migration in parts of the
mine;
— The findings of the ground investigation have not changed the high level of risk
associated with the mine workings beneath residential areas;
— The ground investigation has confirmed the proposed treatment methodology
comprising bulk infilling of open voids and compaction grouting of collapsed ground
although the investigation has indicated the need for a greater proportion of compaction
grouting than originally assumed at feasibility stage;
— The ground investigation has not identified any additional environmental issues for the
treatment works with regard to groundwater as the original floor of the mine appears to
be at least 8 m above the highest groundwater elevation of 55.76 m AOD and
contamination as the ground investigation has not revealed any significant soil
contamination at the site, although the possibility of limited contamination associated
with residential use of the site or previous mining activities exists;
— The site access limitations highlighted in the Feasibility Study Report were experienced
by the intrusive ground investigation works including the presence of mature trees
across the site which will need to be considered during the design of the treatment
works;
The design phase ground investigation has enabled the boundary of the area to be treated to be
defined. The intrusive ground investigation has identified a number of open voids in the vicinity
of the shafts in the southeast corner of Chantry Lane Copse suggesting that treatment of the
mine workings in this area will predominantly consist of bulk infilling. For the remainder of the
mine, where the majority of the interpreted mineworkings appear to be either partially or fully
collapsed or in parts infilled with backfill material, compaction grouting of the collapsed ground
will be required, although consideration will need to be given to the form of compaction grouting
to ensure effective and flexible treatment where more open backfill/collapsed ground is
encountered.
Estimated value excluding VAT: 1 200 000 GBP
