The mines in our country are complex in geography and shape and because of its small scale, accurate surveying performance and 3D modeling are necessary for mine development and management and mining plans. However, due to the data acquisition and processing technology and economy, the existing methods are currently used. The structure, mining, and mining area of the mine are recorded and managed based on the 2D drawings. As a result, it is true that there is risk of accidents caused by problems of accuracy as well as waste of personnel and time. In recent years, research data on geology and geospatial information on mines have been integrated into a database in foreign countries, and they are used for mine management and mining planning. In this study, we tried to construct spatial information for mining management and mining plan using laser scanner. Through research, spatial information about the mine was effectively obtained and produced data modeled through data processing. The 3D model for mining mines is expected to be a valuable tool for establishing and operating a safe mining plan for mines.

This study examined and analyzed several mine management software programs developed in domestic and oversea countries. In the oversea countries, many companies have developed and commercialized mine management softwares such as Dispatch, $Cat^{(R)}$ $MineStar^{TM}$ and FARA. These softwares provide many functionalities including real-time machine tracking, machine assignment optimization, productivity management, equipment health monitoring and remote control. For the domestic cases, this study reviewed two software programs (i.e., GEMISIMS, Truck-Shovel fleet optimization) developed by several researchers because there is no mine management software currently commercialized in Korea. In addition, this paper reports the two cases at the Jwaneng mine in Botswana and at the Robinson mine in United States where mine management software programs are used to support mine operations.

This study introduces $M_{(i,j,k)}BCP$ (Mining Business Continuity Planning) which is the smart management system of mine disasters to achieve the safe and eco-friendly mining. Where, 'i' is mine kinds, 'j' is mining processes, and 'k' is risks at process respectively. By specifically setting 'i=1=limestone mine', this study also suggests that $M_{(i,j,k)}BCP$ is the smart management system of limestone mine. Mining risks used in this study were obtained from professional survey and literature review. This study classified these risks by five different mining processes and reduced risk numbers approximately 60 to 26. And they were all allocated into $M_{(i,j,k)}BCP$ and assessed. To do assess risks, this study used four risk indexes which are probability, casualty, facility loss, and discontinuity respectively. By the results of the assessment of risks, results could be four specific groups based on their causes and impacts. In addition, one of the results showed that the most possible risks at limestone mine was the roof-fall and rock-fall in digging process. This result means that $M_{(1,2,1)}BCP$ should be established as a first priority at limestone mine.

Mining is important as a national key industry that supplies energy and raw materials that are the basis for industrial development. On the other hand, mine development is necessarily accompanied by mineralization, for example, ground subsidence, heavy metal pollution, and water pollution. The mine hazard has a large range of damage, and it takes much time and cost to recover. In addition, there is a need for systematic mining management in order to prevent damages from occurring continuously. In this study, the present status of domestic mining industry and geospatial information construction technology for mining management were investigated. 95% of the mines surveyed were nonmetallic, and limestone mines accounted for 67%, and the constructed mine spatial information is not constructed with 3D geospatial information due to 2D current status, section, and geological map. Considering the results of the survey and analysis of 3D laser scanner and characteristics of Korean mine, handheld scanner is considered to be the most suitable method for constructing mine geospatial information. In addition, the data acquired through the 3D laser scanner can effectively visualize the object, and it can contribute to the systematic management of mining because it can be used for various purposes such as generation of drawings and calculation of volume.

Recently Honam high-speed railroad line is constructed in southern part of Korea. This line is for next generation HST named HEMU-430X. But there is a limestone mine near this line and this mine will make a process to dig a passageway under the railway line. In this case, safety of railroad system and stability of mine are crucial problems on both sides. By measuring mine blasting vibration and calculating regression equation, effect of mine blasting to train running is investigated quantitatively. 0.5 kine (cm/sec) is applied as a management specification of vibration based on field measurement. In this study, changes of blasting patterns are suggested to control vibration of mine blasting. And the effect of train vibration to mine is also invesitigated by numerical analysis.

국내 휴ㆍ폐금속광산 주변지역을 대상으로 광산활동으로 인한 독성 중금속 원소들의 주변 환경 유출과정 및 정도를 규명하여 생활에 미치는 환경오염의 가능성을 조사하는 환경지구 화학적 연구가 지속적으로 이루어지고 있다. 이들 중의 대부분은 적절한 환경복원시설이 설치되지 않아, 방치된 광미와 폐석에 의해 주변지역의 환경오염이 발생되는 것으로 보고되고 있다. 국외의 경우 광산활동의 주요한 폐기물인 광미와 폐석에 대한 매립 및 처리 모델 개발, 침출수 관리 등 다양한 환경오염 방지 및 복구 연구가 수행되고 있다. (중략)

비교적 한정되고 정해진 구역에서 오염물질이 배출되는 것을 점오염이라고 하는 반면, 비점오염은 도시, 농지, 산지, 등 불특정 구역에서 오염물질을 발생시킨다. 점오염에 관한 오염관리가 체계적으로 시행되었던 이전과 달리 최근에는 비점오염에 대한 대책이 시급해짐에 따라 정부는 비점오염에 대한 중요성을 유념하여 한강수계를 대상으로 오염총량관리제를 시범적으로 실시하였다. 환경부는 기존 비점오염원 원단위 부하를 세분화 하여 오염총량제도의 정확도를 향상시키기 위해 노력하고 있다. 우리나라의 비점오염의 관한 연구 중 광산(탄광)지역의 관한 연구는 매우 적다. 본 연구는 광산(탄광)지역의 장기간의 유량 및 수질 모니터링을 통하여 계절별 배출되는 비점오염물질의 유량을 비교하고, ESTIMATOR 모델 방법으로 T-N과 T-P를 분석하였다. 본 연구를 통하여 광산(탄광)지역의 장기적인 모니터링 수행으로 비점오염부하 산정의 유용한 자료로 활용할 수 있을 것으로 판단된다.

In South Korea, Mine industries were encouraged to obtain the natural resource from 1960 to 1980. However, the depletion of natural resource and decreasing price have been caused by the voluntary closure of non-economical mines and a cut of their production since 1990. Harmful wastewater containing such heavy metals as iron, aluminum, arsenic, and cadmium are being discharged from abandoned pits and waste stone and tailing dumping sites following the closure of mines. Therefore, the objective of this paper suggests a policy of mine hazard prevention(PMHP) and method that allows the combination of new spatial data and as well as collected data on resources for the sustainable mine reclamation and management using EGIS/MGIS technique to develop an integrated plan and management techniques.

In recent years, as safety management in underground mines has become more important in the worldwide, mine safety management technologies combining information communication technology such as real-time worker position tracking, monitoring system and equipment remote control have been developed. Wireless communication system is mainly applied to these technologies for the flexibility of network configuration. There are some cases the monitoring system was installed in domestic underground mines, but, it is necessary to develop the technology more suitable for domestic mining standard. In this study, we developed the real-time environmental monitoring system using ZigBee technology and examined the result of application to domestic limestone mine. Furthermore, applicability of the developed environment monitoring system to $VentSim^{TM}$ LiveView was checked. This study is expected to contribute to the related studies like the optimization of the ventilation system in underground mines.
