Abstract

Tin ore washery Sn) is less than the maximum will affect the waste of precious minerals togethertailings resulting in increased levels of tin in the tailings. This is certainly a serious problem for thecompany, the impact of the loss will be visible both from time, labour, etc. And certainly not inaccordance with the target company based on Standard Operating Procedure (SOP). To determinethe levels of Tin (Sn) is still contained in the tailings, the tailings assessments conducted usingmicroscopic analysis.Tailings samples studied came from washery tailings back to the concentratefrom the mining and leaching earlier in Dredger (KK) and Ship Suction (KIP) is brought to the Tin OreProcessing Center (PPBT). Cassetrite or primary mineral Tin (Sn) dominant in the size fraction (+ 50# -20 #) with a percentage weight of 1.176%, and the largest number of samples contained in thetailings coming from Ships Suction (KIP) 4 that is equal to 2.61%. Cassetrite for the weightpercentage of all samples of the tailings is 3:09% and obtained his Levels is 2:44% Sn. The resultsobtained are presented in tables and graphs. Based on microscopic analysis and calculation of Sn inthe whole sample of tailings Dredger (KK) and Ship Suction (KIP), the results turned out to be not inaccordance with the Standard Operating Procedure (SOP) of the company is 1%.

Abstract

The position of Majenang-Bantarkawung region become important and strategic because has a lot ofmineral and coal resources. However, there is no effort in mining area regulation to optimalizationmanagement of mining resources who can useful for people prosperity. Mining zonation of Majenang-Bantarkawung make with weighting and scoring in determination of mining parameters thanprocessing the parameters with overlay method. The parameters are : Land height, Land elevation,Disaster-prone areas, Overburden thickness, Ground water, River area, Water infiltration areas,Forest areas and Agricultural area. According to overlay of 10 mining parameters, Majenang-Bantarkawung mining zonation can be divided into can be permitted to mined, can be permitted tomined with certain condition, and can’t be permitted to mined. Banyumas regency has 61 distributionof mining resources location. Cilacap regency has 75 distribution of mining resources location. Brebesregency has 53 distribution of mining resources location.

Abstract

Management of post mining land become serious concern for government in current time. Post miningarea that located in Ngablak village, Cluwak districts of Pati is one of post mining areas that did notmanaged and creates problems to civilian and village government, for example are safety andenvironment problems. Safety of environment disturbed because of mining activities that finished andcreated unstable slope (potentially landslide) caused by land dredging. To solve this problems,government need to make some research about stability of slope and studies about method ofanalysis which can increase the safety factor of slope. Slope stability analysis can be done with Side6.0 software which needs laboratory result data of soil mechanics. Methods that can increase slope’ssafety factor can be installation of retaining wall and cut and fill method that make the slope becometerraces. Efficiency of method that will be selected, can be tested by using Slide 6.0 software.Installation of retaining wall could increase the safety factor’s value become 1.103, this valuerepresents that the slope is still potentially to be landslide. However, cut and fill can increases safetyfactor’s value become 1.330, that representing slope condition is stable and safe.

Mining activities iscommonlyto work with the problem of deformation or rock movement, this is causingthe shift of rock mass and generated in the occurrence of landslides activity. Slope Stability Analysisrequired that the slope in stable condition. Therefore, stable bench is needed to prevent failure benchthat bring about interference either tool traffic or loading material during production process. Testing ofUCS value is done on 6 lithology that is on asphalt lithology, mudstone, siltstone, sandstone andclaystone. Based on the results of laboratory testing show that value of cohesion and friction angle togenerate by using Generalized Hoek Brown Failure Criterion method.The values of cohesion andfriction angle in asphalt are 0.080712 MPa and 26.3176 º.

The research was conducted in Cisalak area, Sukmajaya district, Depok city, West Java. The researchwas committed in order to search for water source as a purpose to support the planning in built privateuniversity in West Java. The research aims to know the spreading of the aquifer. The used method isby observing the regional geology of the area and supported by geoelectric measuring and water tabledata.. This research used Schlumberger method which spreaded in 10 measuring points. From thismethod, the assessed litologi were clay, tuff sandy, and conglomerat. The underground correlationwas committed in four sections. The aquifer generally tend to spread from the central from west toeast of the area and from north to south.

Abstract

PT Trubaindo Coal Mining (PT TCM) is a coal mining company located in West Kutai, East Kalimantan.Demolition of overburden layer is done by drilling and blasting can effect results primarily blastingground vibration for highwall slope stability. Controlled blasting activities undertaken in 3000 Pit Block05 using linedrill. Vibration measurement data obtained from the reading apparatus is not necessarilya factor affecting vibration highwall slope stability, but with the direction of propagation horizontalvibrations that cause the decrease highwall slope stability. The maximum horizontal accelerationarising from blasting activities as parameters that play a role in the stability of the slope obtained bylinking the PPA with the equation Amax = 0.5167 x PPA. Therefore, to determine the effect of groundvibration due to blasting for highwall slope stability modeling needs to be done cross-section A-A ', BB',C-C ', D-D' and E-E '.

Majenang Groundwater Basin is located in Cilacap Regency, Central Java. There is an increase of itsusage every year. Because of that, it is necessary to make groundwater zonation to get an overview ofthe potential zonation, specifically in unconfined aquifer. The methods used in this study is measuringwater table, sampling 17 samples of groundwater and pumping test to get the quantity of groundwater.Based on the measurement of known water table, it flows from the side of basin to the center of basin.It has a value of water level between 0.1-4.5 mbgl and water table 33.3-119.9 masl. Pumping test dataprocessing generates characteristic data aquifers, with value of transmisivity (T) is 2.9-11.3 m2/day,hidrolic conductivity (K) is 0.7-4.9 m/day, maximum debit is 2.3-3.6 L/day and optimum debit is 2.0-2.9L/day. Based on the result of quantity data, it has a medium potential zone for the unconfined aquifer.

Abstract

Rare earth element REE is very potential future prospect mineral resources in Bangka Island, hence awell developed REE must have a high economic value in the future. As one of the biggest region thatproducing tin ore mining (cassiterite) for hundreds of years, REE potential not yet explored andexploited well until now days in Bangka Island, and was left abundant in ex-mining area. They carriedout from the tin ore mining and become mine waste or tailing and then through the stream flows to besuspension or bed load sediment. The aim of this study is to identify the present rare earth Ce and Ybased on shallow surface sediment samples and their spatial distribution from a number of mineponds called kolong. Primary data collection of shallow surface sediments has been collected onKolong Argotirto and Menjelang West Bangka District, Kolong PLN and Merawang in Bangka District,Kolong Rentensi Kacang Pedang and Pedindang in Pangkalpinang City. Geochemical sedimentsanalysis just for identification the presence of rare earth Ce and Y. Rare earth element of cerium(Ce) just presence in a few sample sediment, but for yittrium (Y) almost presence at all shallowsurface sediment 0,9 - 31,6 ppm. The spatial distribution of rare earth Ce and Y show heterogeneity inlaterally.
