The two-component backfilling system is the most frequently used method to fill the annular gap created during the shield machine advancement. This gap, due to the head overcut, the shield thickness and conicity and the tail brushes size should be filled continuously in order to avoid mainly surface displacement and linings movements. Nowadays this technology is the most chosen due to operative (both...


In mature oilfields, decommissioned oil and gas wells with depths reaching approximately 5000-6000 metres represent good candidate structures for geothermal heat exploitation, as they can provide useful access to subsurface geothermal energy resources. Comprehending the possibility to economically harness geothermal energy by means of coaxial WBHEs is bound to the main features of the physical model,...


Extractive waste (EW) from abandoned mines can pose serious pressure to natural water systems. The harmful effects of EW such as deterioration of water sources by allowing leaching of potentially toxic elements (PTE) into groundwater make it necessary to carry out careful, scientific and comprehensive studies on this subject. The present research used risk analysis approach to study the effect of presence...
