Mining

In order to meet limestone requirement of the three Cement Plants, Jaiprakash Associates Limited has three Captive Limestone Mines – Naubasta Limestone Mine, Jaypee Limestone Mine and Bankuiyan Limestone Mine.

Systematic and scientific mining operations of Jaiprakash Associates Limited are supported with the help of Holder Bank Management Consultancy (HMC), Switzerland by state-of-the art computerized programming – the Computer Aided Deposit Evaluation (CADE) & Quarry Scheduling Optimisation (QSO).

The Mining operations are carried out by fully mechanized open cast mining methods. The equipments used include 153 mm drill machines, hydraulic excavators of 3.8 cum & 4.1 cum bucket capacities, in-situ rock breaker, heavy duty 35 MT carrying capacity dumpers, bull dozers and miscellaneous equipments.

The holes drilled for blasting are charged with bottom initiation using excel detonators to minimize ground vibration and fly rock. A DS-077 Seismograph is used on a continuous basis to monitor ground vibration.

The reclamation and rehabilitation of mined area is a continuous process in Jaiprakash Associates Limited. The hard overburden generated is used to back-fill the area with good topsoil and area is rehabilitated in planned way by adopting large scale afforestation.
