Coal and gas outburst is one of the major disasters in the safety production of coal mine. According to the mechanism of coal and gas outburst, based on the comprehensive analysis of various influencing factors of coal and gas outburst, with the principles of selected early warning indicator, the basic information database of coal and gas outburst warning is constructed, and the information data query function is realized. The mathematical model of coal and gas outburst warning is established by the logistic regression analysis based on the gas concentration, the gas desorption index of drill cuttings, and the initial velocity of gas emission from the borehole. The multivariate information coupled warning was conducted according to the selected early warning indicator system, and the early warning level was divided with the result of early warning. The design and research of the coal and gas outburst warning system are carried out based on the geographic information system (GIS). The coal and gas outburst warning system was verified by taking the Tunliu mine of Lu’an Group as an example. The establishment of the early warning system is a new technical way to the early warning management of coal and gas outburst and can provide a guarantee for coal and gas outburst prevention.

In order to further strengthen the prevention and control of coal and gas outburst in Xinjing Coal Mine, the online comprehensive analysis and early warning index system and rules of coal and gas outburst suitable for Xinjing Coal Mine were studied. Based on the corresponding early warning computer system and guarantee mechanism, a comprehensive early warning system for coal and gas outbursts in Xinjing Coal Mine was established, realizing real-time intelligent early warning of outburst dangers in working faces. The system realizes the standardization and dynamic management of outburst prevention information at the working face, as well as the real-time dynamic update and sharing of outburst prevention information, which improves the efficiency of mine outburst prevention management and the level of mine safety. The actual application of the system in Xinjing Coal Mine shows that the system can provide an effective reference for the comprehensive early warning of outbursts in other outburst mines of Yangquan Coal Industry Group.

Lapango Village is one of the villages in the Sangihe Islands Regency where the settlement is located in a coastal area, precisely in South Manganitu District. The geographical condition of this village is one of the areas close to the Mahangetang Underwater Volcano. From this geographical condition, it is necessary to study the Planning and Spatial Planning of Settlement Areas which are carried out by taking into account the physical conditions of geographic areas that are prone to disasters, especially submarine volcanic disasters, so they must be based on disaster mitigation. The purpose of this research is to obtain a study according to the zoning pattern of community settlements based on Disaster Mitigation. The method used in this research is descriptive quantitative and qualitative, data collection was carried out using a questionnaire to measure Respondents' Perceptions of Disaster Preparedness whose variables and indicators were measured based on Knowledge and Attitudes (PS), Policies, Regulations, and Guidelines (KPP). , Plan for Emergency Situation (RKD), Tsunami Warning System (SPB), Ability to Mobilize Resources (MSD), Next identify the geographical condition of the settlement in coastal areas and the human population inhabiting these settlements.        From this data, analysis is made with a GIS (Geographic Information System) and then followed by a study and concept of zoning for disaster-prone areas and providing information and recommendations to governments and communities in coastal areas in an effort to reduce disaster risk by including Disaster Hazard Map activities ( PRB) into the RPJM for the South Manganitu District, especially for Lapango VillageKeywords: Coastal Areas, Mitigation, Disasters, Lapango Village Abstrak: Desa Lapango merupakan salah satu desa yang berada di Kabupaten Kepulauan Sangihe kedudukan pemukimannya berada di wilayah pesisir tepatnya di Kecamatan Manganitu Selatan. Kondisi geografi dari desa ini merupakan salah satu daerah berdekatan dengan Gunung Api Bawah Laut Mahangetang. Dari kondisi geografis tersebut, maka diperlukan kajian untuk Perencanaan dan Penataan Ruang Kawasan Permukiman yang diselenggarakan dengan memperhatikan kondisi fisik wilayah geografis yang rentan bencana khususnya bencana gunung api bawah laut, sehingga harus berbasis mitigasi bencana. Tujuan dari penelitian ini untuk  mendapatkan kajian menurut pola zonasi permukiman masyarakat berbasis Mitigasi Bencana. Metode yang digunakan dalam penelitian ini adalah deskriptif kuantitatif dan kualitatif, pengumpulan data dilakukan dengan menggunakan kuesioner untuk mengukur Persepsi Responden Mengenai Kesiapsiagaan dalam menghadapi bencana yang variabel dan indikatornya diukur berdasarkan, Pengetahuan dan Sikap (PS), Kebijakan, Peraturan, dan Panduan (KPP), Rencana Untuk Keadaan Darurat (RKD), Sistem Peringatan Bencana Tsunami (SPB), Kemampuan Memobilisasi Sumber Daya (MSD), Selanjutnya mengidentifikasi keadaan geografis dari permukiman wilayah pesisir dan populasi manusia yang mendiami permukiman tersebut.Dari data tersebut dibuat analisis dengan GIS (Geographic Information System) kemudian dilanjutkan dengan dibuat kajian dan konsep zonasi wilayah yang rawan bencana serta memberikan informasi serta rekomendasi kepada pemerintah dan masyarakat yang berada dikawasan pesisir dalam upaya mengurangi risiko bencana adalah dengan memasukkan kegiatan Peta Rawan Bencana (PRB) ke dalam RPJM Kecamatan Manganitu Selatan terlebih Khusus Desa Lapango.Kata Kunci: Wilayah Pesisir, Mitigasi, Bencana, Desa Lapango

Coal and gas outburst is an extremely complex and serious gas dynamic phenomenon. Therefore, building an early warning system based on computer system, safety monitoring systems of coal mines and local area network is a precondition for effectively preventing coal and gas outburst. The early warning system for coal and gas outburst is a complicated system project and has blended together the coal mine safety theory, the information technology and the early warning technology. Combining the hardware conditions, organization management structures and characteristics of preventing outburst technology systems, this paper discusses the principle, logic structure and implementation process of gas outburst warning, devises the software and hardware structure of the warning system and therefore offers theoretical thought and methods for the forecasting of coal and gas outburst.
