fullymechanizedmethodwithafairlyhighdegreeofmechanization.
OpencastminingisidealfortheBhangaonIronOreBlockespecially,inviewoflow
OB/waste thickness and high iron ore thickness. Due to the gentle slope of the
BhangaonironoreBlock,theconventionalhorizontalbenchmethodofmininghasto
be adopted for this deposit.Mining fronts are planned to advance almost north –
South parallel to the surface contours & strike length of the ore. This will allow
miningof fullprofileof the ironore thicknesswith longer strike therebyenabling

4.6 SoilClassification
i) Reliable information on the location extent and quantity of soil & land
resources is the first requirement in planning for the sustainable
management of land resources. The components of land i.e. soil, climate,
water,nutrients&biotawhichprovideavarietyofservicesthatareessential
tothemaintenanceofthelifesupportsystemandproductivecapacityofthe
environment, knowledge of soil fertility status & problems of soil like soil
acidity / alkalinity become essential for development of a sustainable land
useplan.Fertilitystatusofthesoilisprimarily&importantlydependenton

4.7 ClimateDatafromSecondarySources
The climate of this district is characterized by a hot summer, well distributedrainfall during the southwest monsoon season and mild humid post monsoonseason. The year may be divided into four seasons. The cold seasoncommences from December to February. The hot season from March to firstweek of June and themonsoon season is from June to September. October andNovember constitute the post monsoon season or transitional period betweensouthwestmonsoon andwinterseasons.
RAINFALLRecords of rainfall in the district are available for eleven raingauge stations forperiod ranging from 10 to 45 years. The details of the rainfall at these stationsand for the district as awhole are given inTables 1and 2. The average annualrainfall inthedistrict is1288.2mm.DuringthesouthwestmonsoonmonthsJuneto September the district receives about 82% of the annual normal rainfall.August is the rainiestmonthwithanaverage rainfallof327.0mm.Thevariationin the rainfall from year to year is large. In the fifty year period 1951 to 2000,the highestannual rainfallamounting to 144%of the normal occurred in 1956,while the lowest annual rainfall which was 62% of the normal occurred in2000. In the same fifty year period there were 8 years in which the annualrainfall in the district wasless than 80% of thenormal. However, noneofthemwere consecutive years. It is seen from Table 2 that the rainfall was between1001mmand1500mmin28yearsoutof45.On an average there are 65 rainy days (i.e. days with rainfall of 2.5 mm or
more) in a year in the district. This number varies from 57 atManjhari to 71
at Majhgaon. The heaviest rainfall recorded in 24 hours at any station in the
districtwas401.1mmatManjharion21June1977.

TEMPERATUREThere is only one observatory in the district located at Chaibasa. The records oftemperatures and other climatological parameters prevailing at this station may betaken to be broadly representative of the whole district. Temperatures begin todecrease progressively from November. December and January is the coldest partof the year with the mean maximum temperature at abour 25.8°C and the meanminimum temperature at 11.5°C. In association with cold waves, which affect thedistrict in winter months in the wake of western disturbances which move acrossnorth India, the minimum temperature may go down to about 4°C on individualdays.Temperaturesbegin to rise steadily after mid February till first week of June.May and early part of June before the onset of southwest monsoon constitute thehottest part of the year. In May the mean maximum temperature is at 39.3°C andthe mean minimum temperature is at 25.7°C. During this period, maximumtemperature may reach about 45°C on some days. The maximum temperaturedecreases andweatherbecomes appreciably coolwith the advance of the southwestmonsoon by about thesecond week of June and continues to be so throughout theseason. From November temperatures begin to decrease. The highest maximumtemperature and the lowest minimum temperature ever recorded at Chaibasa(observatory) were 46.7°C on 22 May 1948 and 4.4°C on 19 January 1934respectively.HUMIDITYThe summer months March to May are driest part of the year when the relativehumidity in morning is about 50% to 60% and about 30% to 40% in theafternoon. The air is humid in southwest monsoon season, when the relativehumidity is about 80%. During the rest of the year the air is generally dry andmildhumidwiththerelativehumidityatabout50%to70%.CLOUDINESSIn the winter andearly part of summer skies are generally clear or lightly clouded.However, on some days inthewinter in thewake ofwestern disturbancesskies areheavily clouded to overcast. The cloudiness increases from April to southwestmonsoon months, skies are heavily clouded or overcast. Cloudiness decreases fromOctober.WINDSWinds are generally light with slight increase in force in the latter part of summerand southwest monsoon season. In summer and southwest monsoon season windsare predominantlysouthwester1y. In the rest of the year winds arecalm.
