"Prior to suspension of (iron ore) mining activity in September 2012 (in Goa), when prices of minerals were at the peak, in the name of social cost, dust pollution, traffic jam etc, some of the people residing in the vicinity of transportation routes were extorting money from the lease holders and the same was paid by them under distress," Director Mines and Geology department, Prasanna Acharya has said in a statement issued here last week.
Almost 100 people, majority of whom were women, were arrested by police and later released by the police.
Acharya said notwithstanding repeated requests and warnings the protests in various parts continue affecting the smooth resumption of mining activity in the state.
"It is imperative that in upholding the provisions of law and enforcing the directions of apex court (Supreme Court), all organs and instrumentalities of the state should work in perfect harmony," he said.
The Supreme Court had lifted the two-and-half year old ban imposed on mining activity following which firms like Sesa Iron Ore and Fomento Resources began the exports.
Sesa had faced obstruction in transportation of the ore when truckers resorted to strike and blocked the roads late last year.
