# Northern Pits - **Website:** - **Primary alias:** `northernpits.com` ## Description Northern Pits is an independent reference website documenting the history and engineering of coal mining in northern England. Its material focuses on how colliery shafts were sunk, lined and equipped, and how winding systems carried workers and coal between the surface and underground workings. The site brings together historical measurements and practical explanations, including typical 1950s sinking rates, shaft depths and diameters, headgear dimensions, cage loads and pumping volumes. It also describes the stages of shaft construction, from the initial head drift and successive sinking advances to concrete lining, pumping, cabling and installation of the cage. Readers can explore how depth affected construction time, why water management mattered, and how ventilation shafts differed from main winding shafts. The guide highlights Kellingley No.1 in North Yorkshire, which reached 619 metres in 1958 and is identified as Britain’s deepest coal shaft. Northern Pits presents its information as an independent historical resource, drawing on commonly published figures for British colliery practice and recorded shaft depths. ## Industries - 🗺 Reference Materials - 🧪 Science and Education - 🗺 Dictionaries and Encyclopedias _(under Reference Materials)_ - 🧪 History _(under Science and Education)_ ## Logos & icons - logo _(primary)_ — PNG, SVG — [download](https://cdn.brandfetch.io/id-rTMmIJ1/w/820/h/820/theme/dark/logo.png?c=1bxid64Mup7aczewSAYMX&t=1793784273615) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Scooter | #37c2d8 | accent | | Aztec | #0f1c22 | dark | | Mystic | #e2ecef | light | ## Fonts - var(--display) — asset _(custom)_ - var(--display) — asset _(custom)_ --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
