Abstract
The State of Rajasthan has been gifted with unique mineral reserves of dimensional limestone widely known as Kotah Stone spreading over an area of over 55 sq km. The conventional manual mining of Kotah Stone, has been going on since 1945 but all manual. It has not only degraded the environment severally but also proved to be unsafe. Major part of human efforts has been wasted in non-productive jobs causing excessive fatigue and mental stress, inflicting excessive injuries to eye, leg, foot, arm, fingers and spinal cord. Some time in 1992 industry stood on economical threshold when it felt necessary either to develop an appropriate mining technology or close down all mining activities. A responsible mining technology was innovated by the author based on concept of in-situ cutting & sizing prior to splitting. The process has eliminated many hazardous manual process resulting in sharp reduction in accidents human fatigue and stress. Frequency of accident has reduce to 1/6<sup>th</sup>: Man days lost per lac sqft of production has also reduce from 36.6 to 13 only. Major part of non-productive effort has been converted in productive increasing productivity by 3.5 times. It has also created cool and clean working environment which keeps worker calm and tolerant and alert against any danger. The technology proved to be blessings for all stake holders. The innovation has fulfilled objectives defined for Responsible mining such as respect for human rights and aspirations of affected community, providing safe, healthy, and respectful workplace, mininimising harm to environment and leaving positive legacy.

Loss of human life or limb is the most painful, tragedic and irreparable event in life
Mining is one of the most hazardous industry where we fight against the nature. As it is nature rests in full equilibrium but any excavation or extraction disturbs the equilibrium leading to accidents endangering the human life
At times there are unpredictable or unforeseen natural causes. Some such conditions had prevailed in dimensional limestone (Kotah Stone) mining which employing large workforce
Summary
Loss of human life or limb is the most painful, tragedic and irreparable event in life. At times there are unpredictable or unforeseen natural causes Some such conditions had prevailed in dimensional limestone (Kotah Stone) mining which employing large workforce. Separating layers from natural bondage with layer using crowbars, Splitting the non -dimensional chunk of Kotah Stone using chiesel and hammer along natural cleavage planes to yield thin splits,. Due to large production waste lying on working floor many injuries/ even fatal accidents due to slipping and knocking down while carrying head load we're common cause of accidents. Many accidents had taken during transfer of product as headload outside the pit due to accidental breakage of slab or slipping/ knocking down due to uncleaned floor
