From the moment you step into its main tunnel, you enter a different world—one where the walls glisten, the air is pure, and the story of salt unfolds around every corner. In this comprehensive guide, we will delve into every aspect of the khewra salt mine, from its ancient origins and geological formation to the practical details of visiting this underground wonder.
Understanding the Khewra Salt Mine Location
The khewra salt mine location is situated in the Pind Dadan Khan Tehsil of Jhelum District, in the Punjab province of Pakistan . More specifically, it lies in the town of Khewra, which has grown around the mine and is often called the “Kingdom of Salt” . The geographical coordinates of the mine are approximately 32°38′52.58″N 73°00′30.22″E .
The mine is embedded within the Salt Range, a mineral-rich mountain system that extends about 200 kilometers from the Jhelum River south of the Pothohar Plateau to the Indus River near Kalabagh . This range is a geological wonder in itself, rising from the Indo-Gangetic Plain and containing some of the most ancient rock formations in the subcontinent .
The khewra salt mine location is about 160 kilometers from both Islamabad and Lahore, making it accessible for day trips or overnight stays from Pakistan’s major cities . The mine entrance sits at approximately 288 meters (945 feet) above sea level, and the tunnels extend about 730 meters (2,400 feet) into the mountain from the entrance . The entire underground mine covers an area of approximately 110 square kilometers (42 square miles), creating a vast labyrinth of tunnels and chambers that visitors can explore .
The khewra salt mine location in the Salt Range is significant not just for its salt but for its position within a unique geological and ecological zone. The surrounding area is characterized by rugged hills, deep ravines, and sparse vegetation, creating a dramatic landscape that contrasts sharply with the lush plains of Punjab .
The Geological Marvel of Khewra Salt Mine
To truly appreciate the khewra salt mine, one must understand its geological context. The salt deposits at Khewra are part of the Salt Range Formation, which dates back to the Ediacaran to early Cambrian periods, approximately 800 to 600 million years ago . This makes the salt among the oldest in the world, formed when ancient seas evaporated in a hot, arid climate, leaving behind thick layers of evaporites that were later buried, folded, and faulted by tectonic forces .
The geological story of the khewra salt mine is one of immense pressure and movement. The collision between the Indian and Eurasian plates, which created the Himalayas, also thrust these ancient salt beds southward over younger rocks, incorporating fragments of different strata and creating the complex structures visible in the mine today . The salt layer itself is about 150 meters thick in places, consisting of crystalline halite intercalated with potash salts and overlain by gypsiferous marl and beds of gypsum and dolomite .
What makes the salt from the khewra salt mine so distinctive is its purity and color. The salt is approximately 99% pure halite (sodium chloride), with trace amounts of calcium, magnesium, potassium, and various minerals including iron, zinc, copper, manganese, chromium, and lead . These trace elements, particularly iron, give the salt its characteristic pink, reddish, or off-white hues . The purest salt is transparent or white, while the iron-rich layers display the beautiful rose and pink shades that have made Himalayan salt famous worldwide .
The geological stability of the khewra salt mine is ensured by the mining method used. Since the late 19th century, miners have employed the room and pillar method, extracting only about half of the salt and leaving the remaining half as massive pillars to support the roof . This technique has proven remarkably effective, allowing the mine to operate safely for over 150 years with minimal collapses.
The Rich Tapestry of Khewra Salt Mine History
The khewra salt mine history is a fascinating narrative that spans over two millennia, involving ancient armies, Mughal emperors, Sikh rulers, British colonial administrators, and modern Pakistani enterprises. Understanding this history adds depth to any visit.
Ancient Discovery: Alexander’s Horses
The most romantic tale in khewra salt mine history begins in 326 BC, when Alexander the Great crossed the Jhelum and Mianwali region during his Indian campaign . According to legend, the salt reserves were discovered not by Alexander himself, but by his army’s horses. The horses were found licking the stones, and ailing animals recovered after consuming the rock salt . This observation led to the realization that the area was rich in salt, though large-scale extraction would not begin for many centuries .
Mughal Era: Trade and Craftsmanship
During the Mughal era, the khewra salt mine began to gain commercial importance. Salt from Khewra was traded in various markets across the subcontinent and as far away as Central Asia . The Mughals also initiated the practice of using rock salt to create artistic and decorative items, with craftsmen fashioning tableware, ornaments, and decorative pieces from the translucent material . This tradition would continue and flourish in later centuries.
Sikh Period: Control and Revenue
Following the decline of the Mughal Empire, the khewra salt mine came under Sikh control. Hari Singh Nalwa, the Sikh Commander-in-Chief, shared the management of the Salt Range with Gulab Singh, the Raja of Jammu . The former controlled the Warcha mine, while the latter held Khewra. During Sikh rule, the salt quarried was both consumed locally and used as a significant source of revenue .
British Development: The Birth of Modern Mining
The most transformative period in khewra salt mine history began in 1872, when the British, having taken control of the region, initiated systematic development of the mine . They found the existing operations inefficient, with irregular and narrow tunnels that made movement difficult and dangerous. The water supply was poor, there was no storage facility for mined salt, and the only access road was over difficult, rocky terrain .
To address these problems, the British government leveled the road, built warehouses, provided a water supply, improved the entrances and tunnels, and introduced better mechanisms for salt extraction . The main tunnel at ground level was developed by H. Warth, a mining engineer, and remains in use today . It was during this period that the mine became known as the Mayo Salt Mine, in honor of Lord Mayo, who visited it as Viceroy of India .
The British also introduced the narrow-gauge Khewra Salt Mines Railway, which used small rail cars to transport salt from deep within the mine to the surface . Some of these historic tracks are still in use, now serving tourists as well as carrying salt .
Post-Independence Era
After Pakistan’s independence in 1947, the khewra salt mine underwent several administrative changes. It was initially managed by the BMR until 1956, then by the PIDC until 1965. Following the India-Pakistan war of 1965, the WPIDC took over administration . Finally, in 1974, the Pakistan Mineral Development Corporation (PMDC) assumed control of the mine, which remains the largest source of salt in the country .
Today, the khewra salt mine produces more than 350,000 tons of salt per annum, accounting for nearly half of Pakistan’s total rock salt production . At current extraction rates, the known reserves—estimated between 82 million and 600 million tons—could last for another 350 years .
The Mining Process: From Mountain to Market
Understanding how salt is extracted from the khewra salt mine adds another layer of appreciation for this remarkable place. The mine comprises nineteen stories, of which eleven are below ground level . The total length of its tunnels is about 40 kilometers (25 miles), creating an underground network that would take days to fully explore .
The room and pillar method used in the khewra salt mine is both efficient and safe. Miners excavate salt from large chambers while leaving substantial pillars of salt in place to support the overlying rock . This technique ensures structural stability while allowing access to the richest salt deposits. The temperature inside the mine remains a constant 18–20°C (64–68°F) throughout the year, creating a comfortable environment for both workers and visitors .
Once extracted, the salt follows several paths to market. Some is crushed and processed for industrial and culinary uses, including the production of brine and table salt . A significant portion is used by the AkzoNobel soda ash plant, which has operated since 1940 . The most visually appealing salt, with its characteristic pink and red hues, is crafted into decorative items such as lamps, vases, ashtrays, and statues . These products are exported to the United States, India, and many European countries, carrying the name of the khewra salt mine Pakistan around the world .
