The main question to be examined in these matters is whether the
mining activity in area upto 5 kilometers from the Delhi-Haryana border on the Haryana side of the ridge and also in the Aravalli hills causes environment degradation and what directions are required to be issued. The background in which the question has come up for consideration may first be noticed. The Haryana Pollution Control Board (HPCB) was directed by orders of this Court dated 20th November, 1995 to inspect and ascertain the
impact of mining operation on the Badkal Lake and Surajkund -
ecologically sensitive area falling within the State of Haryana. In the report that was submitted, it was stated that explosives are being used for rock blasting for the purpose of mining; unscientific mining operation was resulting in lying of overburden materials (topsoil and murum remain) haphazardly; and deep mining for extracting silica sand lumps is causing
ecological disaster as these mines lie unreclaimed and abandoned.
