Estimation the Q-Value and some Mechanics Parameters of Fifth Caves in a Haditha Area to Determine their Suitability for Underground Storage

The main purpose of this research is to identify the rock mass quality fifth caves in Haditha area using method, In order determine suitable way support and use them for purposes underground storage . first cave located village Aloos, second third are Khafajia area, fourth Barwana Al-Subhani area. Q system based on six parameters direction, spacing, aperture, roughness, condition discontinuities, it also depends groundwater RQD ,were determined by geological field study. Fair According system. Caves can be used storage, but not all materials, as they solid well placing steel, plastic or concrete tanks them. It form small warehouses because these places characterized conditions that differ from surface terms temperature, help provide a sustainable environment due energy therefore lack harmful substances emitted atmosphere.
