Exploration of Siling iron ore deposit in Shanxi Province

Often in deposits developed by underground mining, the task is to control the state of the earth's surface within the mine field. And this problem is even more acute in the case of combined open-underground mining. The Goroblagodatskoe iron ore deposit has been developed by a combined method for more than 40 years. The article describes the methodology and results of applying the geophysical diagnostic method at a mining facility developed by a combined open-underground method - the spectral seismic profiling method (SSP). The application of this method is justified. This method has shown its sufficient efficiency in terms of time costs and sufficient reliability for local studies. The results of field and desk studies are obtained, an assessment of the nature of the object is given, which justifies the use of further measures for the safe development of the object.

Oolitic Ironstone

The Bhainskati Formation of the Tansen Group in the Palpa area is known for hematite iron ore deposit for long time. A prominent band of hematite of about 1-2 m thickness and extending >5 km was identified in the upper part of the Bhainskati Formation in the present study. The band is repeated three times in the area by folding and faulting. Petrographic study shows that it is oolitic ironstone of sedimentary origin. Main minerals in the band are hematite, goethite, quartz, calcite, siderite and albite. Hematite content varies considerably among samples and occurs mainly as oolite and cement. The Bhainskati ironstone with its ferrous mineral assemblage and well-rounded texture of the ooids suggests shallow marine environment (prodeltaic to estuarine) with reduced clastic input.
