Khewra Salt Mines: A Natural Wonder of Pakistan
The Khewra Salt Mines, located in the Punjab province of Pakistan, are one of the largest and oldest salt mines in the world. The mines are a major tourist attraction and a significant contributor to Pakistan's economy. In this article, we will explore the history, geology, and attractions of the Khewra Salt Mines.
History of Khewra Salt Mines The Khewra Salt Mines have a long and fascinating history that dates back over 200 million years. The mines were formed during the Jurassic era, when the Indian subcontinent collided with the Eurasian plate, resulting in the formation of the Himalayan Mountains and the creation of a large salt deposit.
The salt deposits were first discovered by the armies of Alexander the Great in 326 BCE. However, it was not until the Mughal era that the mines were extensively excavated and salt production began on a large scale.
During the British colonial era, the Khewra Salt Mines were further developed, and modern mining techniques were introduced. Today, the mines are operated by the Pakistan Mineral Development Corporation (PMDC) and are a major source of revenue for the government.
Geology of Khewra Salt Mines The Khewra Salt Mines are located in the Salt Range, a hill system that stretches for over 300 kilometers across the Punjab province. The Salt Range is composed of a variety of rocks, including salt, gypsum, and limestone.
The salt deposits at Khewra are estimated to be over 600 million years old and are formed from the evaporation of ancient seas. The salt is extracted from the mines through a process known as room and pillar mining, where large caverns are created to extract the salt.
Attractions of Khewra Salt Mines The Khewra Salt Mines are a popular tourist destination, attracting visitors from all over the world. Some of the attractions of the mines include:
Salt Caverns The salt caverns at Khewra are a breathtaking sight, with towering walls of salt that stretch up to 30 meters high. Visitors can walk through the caverns and marvel at the stunning formations.
Salt Lake The salt lake at Khewra is a picturesque spot, where visitors can see the salt water sparkling in the sunlight. The lake is also home to a variety of birdlife.
Salt Museum The salt museum at Khewra is a great place to learn about the history and geology of the mines. The museum features exhibits on the mining process, as well as artifacts and relics from the Mughal and British eras.
Shopping Visitors to the Khewra Salt Mines can also shop for souvenirs, including salt lamps, salt crystals, and other handicrafts.
Economic Importance of Khewra Salt Mines The Khewra Salt Mines are a significant contributor to Pakistan's economy, generating millions of rupees in revenue each year. The mines provide employment to thousands of workers and support a range of industries, including textiles, leather, and food processing.
Challenges Facing Khewra Salt Mines Despite their economic importance, the Khewra Salt Mines face a number of challenges, including:
Environmental Concerns The mining process at Khewra has raised concerns about the environmental impact of the mines. The extraction of salt has led to subsidence and land degradation in the surrounding area.
Safety Concerns The Khewra Salt Mines have also raised concerns about worker safety. The mines are prone to accidents, and workers have been injured and killed in explosions and rockfalls.
Declining Reserves The salt reserves at Khewra are declining, and the mines are expected to run out of salt in the next few decades. This has raised concerns about the long-term sustainability...
The Khewra Salt Mine is excavated within the base of a thick layer of highly folded, faulted, and stretched Ediacaran to early Cambrian evaporites of the Salt Range Formation. This geological formation consists of a basal layer of crystalline halite, which is intercalated with potash salts. This basal layer is overlain by gypsiferous marl, which is covered by interlayered beds of gypsum and dolomite with infrequent seams of oil shale. These strata are overlain by 200 to 500 meters (660 to 1,640 ft) of Neoproterozoic to Eocene sedimentary rocks that have been uplifted and eroded along with the Salt Range Formation to create the Salt Range at the southern edge of the Pothohar Plateau. The Ediacaran to early Cambrian evaporites of the Salt Range Formation have been thrust southward over Neoproterozoic to Eocene sedimentary rocks by many kilometers, which tectonically incorporated fragments of the underlying younger strata within these evaporites. The Salt Range is the southern edge of a well-described fold-and-thrust belt, which underlies the entire Pothohar Plateau and developed south of the Himalayas as a result of ongoing collision between India and Eurasia.
The Khewra Salt Mine is also known as Mayo Salt Mine, in honour of Lord Mayo, who visited it as Viceroy of India. The salt reserves at Khewra were discovered when Alexander the Great crossed the Jhelum and Mianwali region during his Indian campaign. The mine was discovered, however, not by Alexander, nor by his allies, but by his army's horses, when they were found licking the stones. Ailing horses of his army also recovered after licking the rock salt stones. During the Mughal era the salt was traded in various markets, as far away as Central Asia. On the downfall of the Mughal empire, the mine was taken over by Sikhs. 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. The salt quarried during Sikh rule was both eaten and used as a source of revenue.
In 1872, some time after they had taken over the Sikhs' territory, the British developed the mine further. They found the mining to have been inefficient, with irregular and narrow tunnels and entrances that made the movement of labourers difficult and dangerous. The supply of water inside the mine was poor, and there was no storage facility for the mined salt. The only road to the mine was over difficult, rocky terrain. To address these problems the government levelled the road, built warehouses, provided a water supply, improved the entrances and tunnels, and introduced a better mechanism for excavation of salt. Penalties were introduced to control...
