Strata control is a major concern during underground coal mining and needs special attention. Strata control related incidents like fall of roof and sides continued to remain the single largest cause of fatal accidents in underground coal mines. Between two stages of underground coal mining, viz. development and depillaring; major threat comes during depillaring operation when pillars are extracted i.e., removing of the natural support. Proper addressing of safety issues and its management during depillaring is a great challenge for coal mining industry. This situation during depillaring obviously demands more and more sophisticated and advanced instrumental checking and monitoring of the strata control parameters. Strata control study during depillaring provides data regarding impending abnormal or dangerous conditions/situations in mine workings such as roof fall, development of mining induced stress, bed separation, pillar/stook/rib failure, support performance/failure etc. that action can be taken for safety of the workers and workings. Proper planning, installation of reliable ground movement sensors with continuous data acquisition system, generation of adequate data, proper and timely analysis of data are the factors for success of strata control study programme during depillaring. This paper describes the need for strata control study especially, during depillaring; the most hazardous operation during underground extraction of coal, along with different issues of strata control study like parameters to be measured, sensors to be used, nature of instrumentation and monitoring, etc. including installation of instruments in bord and pillar as well as longwall panels.
