Introduction. Goltas limestone is used in cement production. The design of blast pattern at Goltas limestone quarry is given in two steps. Firstly, the prediction of mean fragment size from Kuznetsov's equation [1] S 50 = A q-0. 8 Qe 1 / 6 (115 / E) 19 / 30 In Eq. (1), A—rock factor, S 50 —mean fragment size (cm), E—relative weight strength …

The market for limestone is remarkably consistent. Quarried limestone can be used to neutralize acidity, so it can be added to soils or lakes. Limestone is used in the iron manufacturing industry, is required for cement, concrete, and mortar mixes, and is heated with sand and sodium carbonate to create glass. 3. It is extremely affordable.

Limestone aquifers represent an important part of groundwater resources in the world. They are usually considered as fractured karstic rock formations. However, a different type, called 'weathered' or 'ghost-rock' karst aquifer has recently been highlighted. In this particular type of aquifer, the karst is not expressed as open conduits but consists …
