Meghalaya Deputy Chief Minister Pretone Tynsong said that after thorough discussions with all stake-holders, it was decided that mining activities by the licensed companies would resume their activities from May 4. He said that the state government has also decided to allow the Export Promotion Industrial Park in Byrnihat, Umiam Industrial Estate, Industrial units in West Khasi Hills, Jaintia and Garo Hills to resume their activities from Monday.

The Meghalaya government on Thursday declared 10 of the state's 11 districts as 'green zones' and allowed inter-district movement as no COVID-19 case was reported from these 10 districts. All the 12 coronavirus positive cases in the mountainous state, including one death of a senior doctor, have been reported in the capital city Shillong that falls under East Khasi Hills district. The mountainous state currently has one active COVID-19 case. Meghalaya exports around 5 to 8 lakh million tonnes (MT) of coal extracted from underground pits and bowels to Bangladesh every year at a cost of 52 dollars per MT. The Bangladesh government had on a number of occasions citing high sulphur content in coal mined from Meghalaya which causes pollution. Subsequently, the ban was lifted by that country as the users, mostly the brick kilns, preferred Meghalaya coal due to its low ash content. According to an official report, more than 33 lakh tonnes of coal have been exported from Meghalaya to Bangladesh since the ban on rat-hole coal mining was imposed by the National Green Tribunal (NGT) in April 2014. The NGT had banned unscientific and ecologically unsafe rat-hole mining of coal in Meghalaya though it intermittently allowed transportation of already mined coal from time to time. Rat-hole mining involves digging of narrow tunnels, usually 3-4 feet high, for workers to enter and extract coal.The horizontal tunnels are often termed "rat-holes", as each just about fits one person. At least 17 people had killed on December 13, 2018 in one of the hundreds of rat-hole mine. /IANS
