HISTORY
Rock Salt was already in use of the local population when in 326 BC, Alexander of Macedonia and his army camped along the Jehlum river about 35-40 kilometers away from Khewra waiting to fight a battle with Raja Porus across the river. Alexander’s horses started lick the rocks and thus the Greeks came to know about the Rock Salt deposits in this area. Since then, mining was done by the local Janjua tribes till the arrival of British in 1849. But it was not done on a scientific manner. The Salt was taken from the outcrop of the salt seams exposed to the surface of the hill. Dr. Warth, a British Mining Engineer laid out the main tunnel at ground level in 1872 to have an easy and direct access to the salt deposits, using Pillar and Chamber Method. The method of mining introduced by Dr. Warth is still in practice. Only 50% of salt is excavated from the working seam while the remaining 50% is left there as Pillars for support of the mine.
Production
Khewra Salt Mines are the 2nd largest Rock Salt Mines in the world with estimated total of 220 million tones of rock salt deposits. Today, Khewra Salt Mines produce around 325,000 tons salt per annum. Out of this production, around 220,000 to 240,000 tones is supplied to Imperial Chemical Industries (ICI) Soda Ash Khewra, which was established in 1938. Rock Salt is also supplied to Ittehad Chemicals Ltd. Kala Shah Kaku and a number of other industries. Selected quality Rock Salt is supplied to dealers for animal and human consumption. A reasonable quantity of salt is also exported to many countries including India. Decoration pieces like lamps, vases, ashtrays etc. are also made and exported from Khewra Rock Salt.
As A Tourist Attraction
The first and the main tunnel at ground level developed by Dr. Warth has been converted into a tourist attraction by the Pakistan Mineral Development Corporation (PMDC) since 2002. There are many points of interest for tourists in the mines. They are taken into the mines on an electric trolley train to the first point and then the visitors are shown various unique portions of the mines with attractive shapes, forms and colours. The first stop is a beautifully mosque made of rock salt brick of different colours and shades. A spacious chamber is named as, “Assembly Hall” measuring over 73 meters in height. There are many water tanks filled with saturated brine solution. There is an area of transparent slat of light pink colour known as, “Sheesh Mahal” (the mirror palace). Here, a series of chambers are connected with salt bridges over water ponds, which are illuminated with lights showing wonderful reflection of different colours of salt.
