Time and motion study is a method of time measurement process, from which time wasting in ground support task that involve human interventions, could be reduced. This method was utilised to figure out the efficiency resulted by buffering tasks, as well as to analyse the work cycle produced by supporting crews of Mega Mustika Utama in PT. Antam Tbk. UBPE Pongkor. The results revealed that the efficiency in workhours of ground support task included survey of location, job cards, and time for meals. The daily work cycle begun from change self protection tools at the beginning of the shift to the replacement of self protection tools at the end of the shift. The results also highlighted that the highest work efficiency of buffering tasks was 84.10%, and the lowest work efficiency was 25.83%

PT. Nan Riang is a coal mining company located in Muara Tembesi District, Batanghari Regency, Jambi Province. PT. Nan Riang applied open pit system in its operation, in which Stripe Mine was considerably implemented as the main method. The utilisation of this method would form pits, so that, during rainy days, the water could potentially be stagnant in front. The catchment areas are divided into 6 sections; the 1st catchment area was 0.00929 km2, the 2nd catchment area was 0.06017 km2, the 3rd catchment area was 0.03256 km2, the 4th catchment area was 0.03960 km2, the 5th catchment area was 0.08065 km2, and the 6th catchment area was 0.02596 km2. From the calculation of drainage dimensions, it was highlighted that the water level was approximately 0.26 m, width of drainage was about 0.39 m, width of drainage surface was 0.78 m, wet circumference was about 0.73 m, the depth of was 1.07 m, and length of side was 1.19 m. The pump that is set for the drainage was LCC-H 50-230, with the pumping capacity of 3,405 m3/ hour. These pumps have Total Head of 90 m, with the impeller rotation of 3710 rpm. The amount of water entering the settling pond was 15.80336 m3/ second, with the settling widht of 29.71 m2 pond. Regarding the dimensions of settling pond, in which water could be gathered as calculated, therefore settling pond should be set at 10 m in length, 4 m in width and 2 m in height, with the volume of 237.64451 m3.

One of technical requirements in renewing mining operation permits, according to ‘Peraturan Menteri Energi dan Sumber Daya Mineral Nomor 34 Tahun 2017’, is the balance sheet of resources and reserves. Before the expiration of the production permit of PT. AKAM, it was then needed to calculate the andesite resource in the operation area of PT. AKAM in Sorong, Papua Barat. The Cross Section method is considered to be the best way to estimate the andesite resource because this method can be utilised to find out the layout of the overburden and mineral. The results highlighted that andesite resource in the operation area of PT. AKAM was approximately 405.780.313 m³, with a cover layer of 498,937 m³. The productivity age of PT. AKAM is predicted to be 49,64 years, with the annual production of 8.112 m³

Mineral and coal resources and reserves in the world even in Indonesia need to be known, considering that until now more and more industries need it, so that it can cause a reduction in raw material supply for the industry. To find out the amount of resources and reserves, data or information is needed, so after knowing the relevant information, it is expected to know what strategies to do. The method used is the comparison between Indonesian data and world data so that the percentage of ownership in Indonesia can be known. The results showed that coal in Indonesia was estimated to range from 2% -3% of coal in the world. For metal minerals, Indonesia had 6.08% nickel, 6.82% cobalt, 14.05 lead, 9.63% zinc, 3.33% bauxite, 0.72 iron, 4.63 gold, 16.67% tin , 3.29% copper, 19.17 manganese, 0.44% chromium, 0.17 titanium.

People in Doput village and Misapmeysi villages, based on their local knowlegde and understandings, have different points of view in perceiving problems resulted from mining activities, particularly impacts that have been experienced. In order to find out the villagers’ perception, a questionnaire consisted of questions about language, local knowledge, technology, art, traditional livelihood, religion, and kinship were distributed to 50 respondents in the two villages. The results showed that 74%– 88% of the respondents have good perception in terms of local culture. This is because the respondents assumed that the local culture still existed, and even would be preserved both before and after the limestone mining activities of PT. SDIC Papua Cement Indonesia Manokwari. The average percentage of cultural variables were perceived from good to very good; language (74%), natural knowledge (88%), tecnology (83%), art (74,67%), living livelihood traditional (83,33%), religion (85%), and kinship (84%). In general, the results indicated that the limestone mining in Maruni has been positively perceived by the villagers, espeecially from the culture perspective

Cement plug is a method to place plug to a specific depth used cement to close the well, preventing lost circulation, sidetrack at the begining of directional drilling and to provides a place for open hole test. The cement plug methods used in this research is balanced plug method. This research conducted by collecting data on Well X, in the form of well profile data covering casing and tubing dimension. Furthermore, laboratory data for cement and additives are used. Result of research showed that the total volume of cement slurry needed is equal to 29.455 bbl, the number of sack of cement for cementing the open end interval of 81.4 meters is as much 155 sack of cement, and the total volume of fluid required to push the cement slurry into cementing zone is equal 64.15 bbl.

PT. Haltim Mining is one of the nickel mining companies with sediment resources consist of several layers, namely cover soil, limonite, saprolite and bedrock. About 1.8% of the nickel concentrate would be marketed by the company, but the nickel content sampled for testing by XRF Epsilon 3 tool changes the level between the samples in the Pit and the sample on the stockpile. The results showed that the average level of nickel concentrate sampled at Pit was 1.80%, while the average level of nickel concentrate sampled on Stockpile was 1.75%, with an average difference of 0.09%. Changes in levels were influenced by sampling method, sample preparation and the accuracy of a sampler.

Road is one of the important aspects to support transportation activities. Appropriate road geometry can contribute greatly to the safety and smoothness of transport activities. In addition to the road geometry, water can also affect the condition of haul road, from which it can indirectly affect the transportation activities. Therefore,it is important to conduct an evaluation of the haul road geometry condition based on the AASHTO theory, and to design drainage on the road side of the mine. Road geometry at PT. Sumber Anugerah Buana has not suitable yet based on AASHTO theory. This is proven by using the actual result showing that the the width of straight road was 4 - 7,5 meter, and the width of bend road was 5.3 - 5,5 meter. However, according to AASHTO theory, the width of straight road should be 4,850 meter and the width of bend road should be 7,733 meters. So, it is necessary to add width on straight road in segment IJ and in all segment of bend road. The slope of the mine haul road at PT. Sumber Anugerah Buana already has a safe slope of the road, except the A-B segment and D-E segment that are still above the safe condition, which is more than 15%. PT. Sumber Anugerah Buana does not have drainage, so it is necessary to make channel on the first DTH dimension, that is 0,463 meter wide, 0,701 meter deep, and 0,928 meter wide of the channel surface. Meanwhile, the dimension for the second DTH should be 0, 260 meter wide of the channel bottom, 0.395 meter deep of the channel, and 0,522 meters wide of the channel surface.

Landslide events in an area are manifestations of unstable slope conditions, so that evaluation of slope stability and mapping of areas prone to landslides is very important as an effort to mitigate landslides. In this study the Slope Stability Probability Classification (SSPC) method was used to evaluate slope stability in the Piyungan-Patuk area. which is a rock mass classification system for slope stability which classifies 3 (three) different rock masses through a three-step approach namely: Exposure Rock Mass (ERM), Reference Rock Mass (RRM) and Slope Rock Mass (SRM). Slope stability analysis results on 18 selected slopes obtained probability of slope stability with very low to very high classification with a probability value of stability <0.5 to> 95, where the probability value is strongly influenced by rock mass parameters such as rock strength, discontinuity and weathering rate .
