Abstract

Ground control is one of the most important activities in underground mines to control the roof and side fall injuries in India. Since long wooden prop and cog were being used to support the mines panels, or roadways. Scarcity of timber due to ecological reasons and therefore increase in its cost make the support designer’s or engineers to innovate the alternatives. In Indian mines different types of standing supports like square hollow section (SHS) prop, steel telescopic prop, pit prop, hydraulic prop, steel cogs etc. are being used in longwall as well as bord and pillar mining as per geological conditions of respective mines workings. These props are heavy, cumbersome portability, requiring regular maintenance and not user friendly. Keeping in mind the Indian mining condition, the support should be of greater longevity, light enough for easy portability and requiring less maintenance. Further it should have facility for height variation, sufficient yielding, continuous load monitoring and releasing remotely as coal seam thickness widely various Indian mines. This paper describes the design, working principle, advantages etc. of a slow loading suitable yielding prop with greater longevity, portability, sufficient yielding and continuous load monitoring with its use in varying coal seam thickness by replacing the conventional wooden and steel prop. This newly invented and patented prop has undergone a successful field trial and got the regular approval by the authority who looks after the mines safety i.e Directorate General of mines Safety (DGMS), Government of India
