Reclamation suitability evaluation is the basis for determining the reuse direction of damaged land. Limit condition method is the most widely used method in land reclamation suitability evaluation at present. In this paper, the limit condition method is used to evaluate the suitability of land reclamation of damaged land in Pingdingshan Tianan ten coal mine. The evaluation index of damaged area is determined as six main factors: field slope/land flatness, ponding, depth of collapse, soil texture, thickness of soil layer, irrigation and drainage conditions, and finally determine the reclamation direction of the land to be reclaimed in combination with the overall local land use planning and the overall wishes of local residents.

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.

Cooling Technology

Freeze roadway cooling technology is delivering cold quantity to cooling underground face by storage cooling energy in strata, and the effect of storaging cold is critical. The geographical position and geological condition of coal mine in Heilongjiang Province has remarkable characteristics. The feasibility of freeze roadway cooling measure was demonstrated on temperature, geothermal, constant temperature strata and frozen soil layer, etc. by analyzed its advantage adequately. The measure provides a new idea which suits the native situation for prevent the heat-harm in coal mine, it also has the realistic reference value and is worth popularizing.

User Friendly

Agricultural land use planning should always be guided by a reliable tool to ensure effective decision making in the allocation of land use and activities. The primary aim of this study is to develop a user friendly system on a spatial basis for agricultural land suitability evaluation of four groups of agriculture commodities, including food crops, horticultural crops, perennial (plantation) crops, grazing, and tambak (fish ponds) to guide land use planning. The procedure used is as follows: (i) conducting soil survey based on generated land mapping units; (ii) developing soil database in GIS; and (iii) designing a user friendly system. The data bases of the study were derived from satellite imagery, digital topographic map, soil characteristics at reconnaissance scale, as well as climate data. Land suitability evaluation in this study uses the FAO method. The study produces a spatial based decision support tool called SUFIG-Wilkom that can give decision makers sets of information interactively for land use allocation purposes.This user friendly system is also amenable to various operations in a vector GIS, so that the system may accommodate possible additional assessment of other land use types.

The Impact

PurposeThe purpose of this paper is to examine the perspectives of local residents regarding the impact of the long-duration Hazelwood open cut coal mine fire in rural Australia.Design/methodology/approachA qualitative approach was undertaken involving 27 in-depth interviews with adults who lived in the town of Morwell, immediately adjacent to the coal mine fire.FindingsParticipant concerns focussed upon fear and confusion during the event, the perceived health effects of the smoke, anger towards authorities and loss of a sense of community and sense of security. One of the significant ways in which people managed these responses was to normalise the event. The long duration of the event created deep uncertainty which exaggerated the impact of the fire.Research limitations/implicationsUnderstanding the particular nature of the impact of this event may assist the authors to better understand the ongoing human impact of long-duration disasters in the future.Practical implicationsIt is important to provide clear and understandable quality information to residents during and after such disasters.Originality/valueWhile there is an extensive literature exploring the direct social and psychological impacts of acute natural disasters, less qualitative research has been conducted into the experiences of longer term critical events.
