Supplier Engagement - Phase 2 The Mining Remediation Authority currently has the capacity to treat 220 billion litres of mine water every year. Treating mine water has directly protected and improved over 350km of rivers, protects several important regional aquifers, enhances biodiversity and provides local amenity land. Our mine water treatment prevents early 4000 tonnes of iron solids iron solids and other pollutants entering watercourses or aquifers. Last year 97% of the iron solid waste was recycled or reused. In partnership with the Department for Energy Security and Net Zero (DESNZ), the Department for Environment, Food and Rural Affairs (DEFRA), the Environment Agency (EA), Scottish Environment Protection Agency (SEPA) and Natural Resources Wales (NRW), the Mining Remediation Authority delivers a program of mine water treatment and monitoring across England, Scotland and Wales, ensuring that the mine water is effectively treated before entering natural watercourses. Boreholes are used to improve our understanding of mine water. Our boreholes provide critical water level and quality monitoring data used to assess potential risks to aquifers and surface water bodies. These assessments form the basis of our mine water management strategies with abstraction from boreholes often being key to mine water level control. The Mining Remediation Authority requires a framework agreement for the provision of services relating to the construction and testing of boreholes in former mining areas. The services are anticipated to include borehole drilling, construction, testing, maintenance, cleaning, rehabilitation, technical support and associated works/services. This engagement is the second phase of supplier engagement in which we are seeking to inform the market of our procurement strategy to invite supplier feedback to aid us in building a effective and innovative procurement solution.

The Coal Authority requires specialist technical support to build a predictive hydrogeological and geochemical model to assess the potential impacts of saline rising mine water on surface water and groundwater receptors in the East Midlands. The study area comprises an extensive and complex series of coal workings which are partially flooded and rising. Part of the mine system is currently being pumped and monitored as part of an ongoing hydrogeological test pumping exercise. Specialist modellers and hydrogeological consultants are invited to attend an initial 1 hour meeting with the Coal Authority to discuss possible modelling approaches and what their organisation can offer. An individual meeting will be held with each interested party via Teams with the chance to follow up with an information pack based on the discussions.

The Coal Authority are looking for companies who can provide Mine Management services. If you are interested in this requirement, please fill out the attached registration of interest form and return back to helenbaldwin@coal.gov.uk in the procurement team by Monday 8 August 2022. Introduction - With the increasing need to manage the closure and permanent sealing of both 'shaft' and 'adit' mines, we require suitably experienced and qualified mine management personnel to supervise and manage operational works under The Mines Regulations 2014, including the role of Mine Operator. This may also involve installing/repairing drainage schemes within legacy coal mines and potentially other mineral mines that necessitates entry into the mine. Background - This may require design of and/or management of operations to undertake 'mine closure and sealing' works either directly or to supervise our framework contractors undertaking construction works. We seek expressions of interest to provide qualified personnel with experience of managing mining, mechanical and electrical mining systems and the ability to safely assess and manage operations under The Mining Regulations 2014 and other associated and aligned safety legislation e.g. Construction (Design and Management) Regulations 2015. Objectives; We are proposing to create a procurement framework of technical professionals who have the necessary mining, mechanical, electrical and other relevant skills, knowledge and experience to undertake the role of Mine Operator for works that include the permanent sealing of shafts/adits. This may also include the repair and/or replacement of internal mine infrastructure e.g. support systems and installation of drainage and associated monitoring. These requirements may arise following a mine going into liquidation, so the ability to inspect and assess mining risks and safety status of 'operationally active' mines or closed mines under 'care and maintenance regimes' as well as abandoned mines is key to this opportunity. This potentially requires access to or support from qualified and experienced mining personnel, including: Mining engineers, mining mechanical and electrical engineers, mine surveyors, mining ventilation engineers, mine gas specialists, mine water hydrogeologists e.g. who are able to assess inrush risk and precautionary schemes.

The Coal Authority (the "Authority") is looking to engage a strategic supplier to provide Network Operations Centre (NOC) and Security Operations Centre (SOC) contract for which the procurement is expected to begin in early 2025. This notice is provided to advertise and seek responses to a series of market engagement opportunities that will in turn provide further detail and inform the planned procurement and help shape the requirements.

The Coal Authority (Client) was established by Parliament to undertake specific statutory duties, set out in the Coal Industry Act 1994, associated with licensing coal mining operations; managing property and the historic legacy arising from the ownership of the coal reserves and underground workings; settling subsidence damage claims not falling on coal mine operators and providing access to coal mining information. 1. Background The mine water in the Barnsley-Manvers-Grimethorpe mine water block is thought to be rising. Recovered mine water in this area represents a potential risk to the overlying Permian aquifer, as well as surface water in the area. To assess the mine water regime, and inform future mine water management strategies, a borehole is required that would target the Brodsworth or Bullcroft colliery mine workings. Therefore, the Coal Authority (CA) requires a mine water monitoring borehole to increase the monitoring infrastructure in the area. The data from this borehole will be used to improve understanding of mine water in the Barnsley-Manvers-Grimethorpe mine water block, through water level monitoring and quality sampling. 2. Delivery The CA look to collaboratively engage with landowners to obtain access and a licence to carry out the drilling works. It should be noted that this engagement may take up to a maximum of 15 months, from initial point of contact however, in some cases this is significantly less. With this in mind, the Invitation to Tender is sent out part-way through this timeframe. Nevertheless, and to avoid any delays, the Contract will be awarded with a Contract Award Date and Start Date as two different dates. 3. Engagement Opportunities The CA are always looking for ways to improve and streamline projects. Due to the defined verticality requirements, it is envisaged that the most robust and reliable method of completing the mine water monitoring boreholes is by drilling a pilot hole using a wireline coring system, followed by reaming to the required diameter(s). However, the CA would welcome your feedback on this including any other methods that may be deemed more suitable to guaranteeing verticality such as directional drilling.
