Evaluation of Radiation Hazards Due to Mining Activities in Al Jalamid Mining Area, North Province, Saudi Arabia

This paper presents a study on assessment of water quality. According to a study, mining activities have a significant impact on water quality (lakes, surface water and groundwater), which has become a major problem globally. Due to mining and exploitation processes, lakes can be formed around these mines. Also, these lakes have been formed around the world and are steadily increasing. The purpose of this study is to watch the quality of water from the area around mining activities. This study refers to the, Groapa Burlacu lake around the mining exploitation Targu Ocna, Romania. This lake was formed on the northern bottle of the massive salt, strongly affected by the underground activities. Sampling for the determination the concentrations of Cl- and NaCl from the studied area was made at different depths (0 m, -5 m, -10 m, -15 m, -20 m, -25 m, -30 m, -35 m -40 m). Besides these concentrations, physical parameters of the water (pH, turbidity, electrical conductivity, dissolved oxygen and temperature) were also measured. To determine the physical parameters in the monitored area, sampling was done from four different points of the area and then put together for analysis. These parameters were measured on site using portable equipment. The data on the analyzed concentrations indicate that at depths of less than 5.0 m, the NaCl concentration values are more than 250 g/L.

AbstractIt is a known fact that phosphate rocks have high levels of natural radioactivity due to the presence of large concentrations of radionuclides. This work aims to estimate radiation exposure and dose levels at Al-Jalamid site in northern Saudi Arabia. Al-Jalamid area is one of the largest reserves of phosphate worldwide. Ma’aden, a Saudi Government public company, owns the mine and is responsible for all mining activities. Phosphate and soil samples collected from Al-Jalamid phosphate mining area have been analysed for their uranium and thorium content by an α-spectrometer using radiochemical techniques. The quantity of radon gas was measured both in groundwater and in the atmosphere (indoor and outdoor) at the site using a portable radiation survey instrument. Groundwater samples collected from wells surrounding the mining area were analysed using a liquid scintillation counter in addition to an α-spectrometer. Finally, it is found that phosphate rock concentrate products cannot be utilized economically based on the standards set by the International Atomic Energy Agency (IAEA), since the average activity concentration does not reach the limit set by IAEA and hence are not commercially feasible.

And Control

Mining activities interfere into the natural groundwater chemical environment, which may lead to hydrogeochemical changes of aquifers and mine water inrush disasters. The study of hydrogeochemical evolution processes of underground aquifers is helpful to the prevention and control of mine water inrush. The results show that the study area is mainly impacted by four hydrogeochemical processes: dissolution, cation exchange, desulfurization and reduction, and pyrite oxidation. The Cenozoic aquifers are dominated by carbonate dissolution and desulfurization. The Permian aquifers are impacted mainly by cation exchange and sulfate dissolution, followed by pyrite oxidation. The Carboniferous aquifers are mainly impacted by dissolving sulfate, followed by pyrite oxidation and cation exchange. The hydrogeochemical evolution of the aquifers was controlled by mining activities and tectonic changes, and a certain regularity in space. For the Cenozoic aquifers, sulfate dissolution and cation exchange increase from west to east, and desulfurization weakens. For the Permian aquifers, cation exchange and sulfate dissolution are stronger near synclines and faults, pyrite oxidation is enhanced, and desulfurization decreases from the middle to the east of the mining area. For the Carboniferous aquifers, there is a higher dissolution of rock salt, pyrite oxidation, and cation exchange from west to east, and the desulfurization effect weakens.

This paper presents a new real-time monitoring method based on the explosion source location technique on the underground mining activities in the situation the state can not achieve the full uninterrupted supervision because of the backward monitoring tools and equipment. The supervise mode results in some small coal mines in the profit-driven to ultra-layer or cross-border mining which causes a many of safety accidents. The five acceleration vibration sensors buried underground in the mining area pick up blasting vibration waves coming from blasting tunneling. Every signal acquisition sub-station deals with the according sensor output signals by using wavelet transform to identify the P waves and using energy eigenvalue method to determine the arriving time of P wave to the sensor, then translates the sensor’s spatial and temporal parameters to the principal computer. The principal computer locates the explosion source by the Geiger algorithm and displays the explosion source’s spatial message in the mine’s electronic map. The method is feasible and the positioning horizontal error is less than 10m by field-proven.

Recognition and extraction of mining ground deformation can help us understand the deformation process and space distribution, and estimate the deformation laws and trends. This study focuses on the application of ground deformation detection and extraction combining with high resolution visible stereo imagery, LiDAR observation point cloud data and historical data. The DEM in large mining area is generated using high-resolution satellite stereo images, and ground deformation is obtained through time series analysis combined with historical DEM data. Ground deformation caused by mining activities are detected and analyzed to explain the link between the regional ground deformation and local deformation. A district of covering 200 km2 around the West Open Pit Mine in Fushun of Liaoning province, a city located in the Northeast China is chosen as the test area for example. Regional and local ground deformation from 2010 to 2015 time series are detected and extracted with DEMs derived from ZY-3 images and LiDAR point DEMs in the case study. Results show that the mean regional deformation is 7.1 m of rising elevation with RMS 9.6 m. Deformation of rising elevation and deformation of declining elevation couple together in local area. The area of higher elevation variation is 16.3 km2 and the mean rising value is 35.8 m with RMS 15.7 m, while the deformation area of lower elevation variation is 6.8 km2 and the mean declining value is 17.6 m with RMS 9.3 m. Moreover, local large deformation and regional slow deformation couple together, the deformation in local mining activities has expanded to the surrounding area, a large ground fracture with declining elevation has been detected and extracted in the south of West Open Pit Mine, the mean declining elevation of which is 23.1 m and covering about 2.3 km2 till 2015. The results in this paper are preliminary currently; we are making efforts to improve more precision results with invariant ground control data for validation.

Farming Village

Abstract: Kutai Kartanegara (Kukar) is an area with quite extensive mining concession. However, Kukar is also the only district in East Kalimantan which experienced rice surplus. Although the amount of rice production is not significant, this condition should be appreciated, because in fact, the official releases shows its surplus is distinguish, compare to other district in East Kalimantan. Problems arise when massive mining operations occurred in those region. Some areas suffered real damage, especially agricultural land around the mining area. Damage is no longer a threat, but it has occurred and persisted. This study try to picture Kukar in the context of farming practices in the crush of mining Activities. There are three villages as observational study area, which are, Jembayan Dalam, Sedulang, and Sarinadi. The author’s findings show that in the three villages, it is interesting to observe and to describe how exactly the problem of agricultural land degradation surrounding the mining existed, and how the community respond to this condition. Jembayan Dalam village and Sedulang suffer severe damages, even the land can no longer being used for farming. However, in Sarinadi, the author found interesting findings since as a farming village, its system and social structure which was built by the community is able to shield themselves from the onslaught of the mining financiers. Keywords: Kutai Kartanegara, agriculture land, miningIntisari: Kutai Kartanegara (Kukar) adalah sebuah wilayah dengan konsesi pertambangannya cukup luas, akan tetapi, Kukar juga satu-satunya kabupaten di Kalimantan Timur yang mengalami surplus beras. Walaupun tidak terlalu besar namun harus diapresiasi, karena faktanya, rilis angka-angka resmi pemerintah menunjukkan itu. Persoalannya, dengan masifnya operasi pertambangan, beberapa wilayah mengalami kerusakan yang cukup serius, khususnya lahan pertanian sekitar pertambangan. Kerusakan bukan lagi ancaman, namun sudah terjadi. Kajian ini akan mencoba melihat Kukar dalam konteks bertani dalam himpitan tambang. Ada tiga desa yang menjadi observasi kajian yakni Desa Jembayan Dalam, Sedulang, dan Sarinadi. Temuan penulis dalam tiga desa ini cukup menarik untuk melihat dan menggambarkan bagaimana sebenarnya persoalan kerusakan lahan pertanian sekitar pertambangan, baik problem maupun respons masyarakat. Desa Jembayan Dalam dan Sedulang mengalami kerusakan yang cukup parah, bahkan lahannya tidak bisa digunakan untuk bertani. Namun di luar itu, Sarinadi sebagai sebuah desa pertanian cukup menarik untuk dilihat karena sistem dan struktur sosial yang dibangun oleh masyarakat mampu membentengi diri dari serbuan para pemodal tambang.
