JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objectives

In spite of increasing trend of accidents due to strata control problems in

India, and establishment of “STRATA CONTROL CELL” in all coal mine areas, application of scientific approaches for strata control could not be achieved satisfactorily. Hence, the course aims at specialized techniques for strata control in underground coal mines with topics on safety status, strata behavior studies, organization of strata control cell etc.

Course Outcomes

Future mining in complex geomining conditions demand innovative

strata control technologies to be adopted for safe and stable mining structures. This course gives in depth knowledge to deal with strata control problems, especially in underground coal mines.

UNIT - I

Geo mining conditions: Geological factors contributing to strata control problems in mines, Geo mechanics classification of rocks.

UNIT - II

Safety status: Status of safety in coal mines vis-à-vis strata control problems, assessing the risk from the hazards of roof & side falls.

UNIT - III

Design of support system: Design of support system for development and depillaring workings. Design of support system for long wall workings, application of modeling techniques to strata control problems

UNIT - IV

Strata behavior studies: Instrumentation for evaluation of strata condition in coal mines, Strata control techniques and its application to coal mining industry. Case studies on geotechnical instrumentation and strata control in coal mines. Demonstration of geotechnical instrumentation and computer softwares.

UNIT - V

Organization of strata control cell: strata control cell in mines, Training needs of the first line supervisors for effective implementation of the latest strata control technologies.
