Important Basis

Suitability evaluation is the important basis for scientifically determining the direction of land reclamation. This paper deeply elaborates the goal of land reclamation and the principles of suitability evaluation. land reclamation direction of the project area is initially determines to be cultivated land, forest land, grassland and garden plot based on region land-use planning and analysis of natural factors, socio-economic factors, policy factors of the mining area; the evaluation index system including five involved factors is constructed, and the suitability evaluation of evaluation units is carried out by the comprehensive index method and extreme conditions. Based on above-mentioned evaluation, the land reclamation direction of 14 evaluation units are ultimately determined by comprehensive analysis of the local natural conditions, social conditions and so on.

Abstract Greenhouse gas emissions are a common problem noticed in every mining area just after mine closures. However, there could be a significant local gas hazard for people with continuous (but variable) emission of these gases into the atmosphere. In the Upper Silesia area, there are 24 shafts left for water pumping purposes and gases can flow through them hydraulically. One of them – Gliwice II shaft – was selected for inspection. Carbon dioxide emission with no methane was detected here. Changes in emission and concentration of carbon dioxide around the shaft was the aim of research carried out. It was stated that a selected shaft can create two kinds of gas problems. The first relates to CO2 emission into the atmosphere. Possible emission of that gas during one minute was estimated at 5,11 kg CO2/min. The second problem refers to the local hazard at the surface. The emission was detected within a radius of 8m from the emission point at the level 1m above the ground. These kinds of matters should be subject to regular gas monitoring and reporting procedures.
