Founding of Lynch, Kentucky — 1917

The U.S. Coal & Coke Company, a wholly owned subsidiary of U.S. Steel Corporation, established the town of Lynch, Kentucky in 1917 on a 19,000-acre tract deep in southeastern Harlan County. From the outset, the company designed and built every aspect of the community — from the mine portals to the homes, schools, and public buildings.

At its peak, Lynch held a population of approximately 10,000 residents representing an extraordinary 38 nationalities — immigrants and American-born alike who came seeking work in the booming coal industry of Central Appalachia. It became known as "the world's largest coal camp."

Infrastructure & the Company Town

U.S. Coal & Coke built Lynch as a complete, self-contained community. Public buildings were constructed using cut sandstone, giving the town a permanence uncommon for the era. The company erected a large company store, post office, movie theater, hotel, hospital, churches, and schools — all company-owned and company-operated.

The coal tipple, completed in the 1920s, had a 15,000-ton capacity and processed the enormous quantities of coal extracted daily from the drift mines. Transportation was via the Louisville & Nashville (L&N) Railroad, whose depot still stands on the Portal 31 grounds today.

World Record Coal Production — February 12, 1923

On February 12, 1923, the miners of Lynch, Kentucky made history. Working a single 9-hour shift, they produced 12,820 tons of coal — setting a world record for coal production in a single shift that stood for years. This achievement stands as a testament to the extraordinary skill, endurance, and dedication of the men who worked these mines.

All of the coal produced at Lynch by U.S. Coal & Coke Co. was "captive coal," meaning it was produced exclusively for U.S. Steel's own consumption. It was never sold on the open market, but fed the furnaces of America's industrial engine during one of the greatest periods of growth the country had ever seen.

Highlights: Lynch Plant, 1917–1957

The decades between 1917 and 1957 represented the height of Lynch's coal production and community life. During this period the town thrived — families raised children here, immigrants built new lives, and the mines ran continuously. Despite the company providing healthcare and education, U.S. Coal & Coke maintained firm control over labor organizing, contributing to Harlan County's broader and well-documented reputation as "Bloody Harlan" — a region defined by fierce and sometimes violent labor conflicts.

The drift mines at Lynch were unlike shaft mines — they ran directly into the mountain face horizontally, following seams of coal through the hillside. Portal 31 is one of those original mine entrances.

The Town & People — 1917 to 1926

Background research compiled by Dave Johnson documents the remarkable diversity of Lynch in its early years. Workers arrived from across Europe, the Middle East, and beyond — Italians, Poles, Hungarians, Greeks, Lebanese, and many others — drawn by the promise of steady wages in the coalfields. African American workers also came in significant numbers, often recruited from southern states.

The company segregated housing and facilities by race, a reflection of the era's social norms. Despite these divisions, the communities that formed were tightly knit. Neighbors from dozens of nations shared mountain slopes, raised families side by side, and built a cultural richness that Lynch residents still celebrate today.

Population Decline & Legacy

By 1970, the incorporated town of Lynch had a population of just 1,517 residents — a fraction of its peak. By 1990, that number had dropped further to 1,166 as coal industry mechanization and market shifts reduced the need for large mining workforces.

Today, Portal 31 preserves and shares that legacy. The mine has been rehabilitated and opened to the public as a living museum and underground experience — ensuring that future generations can understand what it meant to work the coal seams of Harlan County, Kentucky.
