In emergency management, emergency exercise is an important means of training response process, improving the ability to organize and coordinate, as well as discovering vulnerable link. Based on dynamic tabletop exercise, this paper illustrates the design of distributed interactive emergency exercise simulation platform (EESP), which is oriented to high level commanders. This platform is capable of training commanders' cooperative command ability by various configurable scenarios under different kinds of emergencies. To provide support for exercise-based training of emergency management, EESP is able to support interaction among multiple users, support cooperative decision-making among commanders, and achieve real-time interaction between commanders and emergency situation. ©, 2015, Xitong Gongcheng Lilun yu Shijian/System Engineering Theory and Practice.

In order to prevent goaf gas swarm into adjacent tunnel because of goaf coal pillar break when working face excavating,this article used FLAC3D numerical simulation software simulate overlying rock and coal pillar stress, plastic zone distribution when the working face excavating,the simulate results shown that,when working face excavated 32m,coal pillar began to break under the effect of excavation,until excavated 48m,almost whole of the coal pillar damaged, so the problem of air leak in coal pillar was serious,it needed strengthening measures to solve that problem.In order to prevent of gas accident and ensure the safety production of coalmine.

Hydraulic fracturing technology , as one of the irrigation measures to increase the coal seam permeability artificially , has its remarkable advantages . This paper mainly uses the methods of theoretical analysis , RFPA2D numerical simulation and field validation to study multi-point fracturing . It proved the reliability and accuracy of multi-point fracturing numerical simulation by comparing multi-point fracturing simulation results with multi-point fracturing field test results . At the same time , it optimized the process parameters of multi-point fracturing site through simulation . Taking the fracturing borehole in a mine's multi-point fracturing field test as the background , a conclusion was drawn from the multi-point fracturing simulations with different water point spacing that when the water point spacing is 3 meters , the fracturing effect is the best . The numerical simulation of optimization results provided a reference for the application and parameter choice of the underground coal mine multi-point hydraulic fracturing technology and thereby succeeded in improving the fracturing effect and gas extraction rate to the greatest degree . This is of great practical significance to the coal mine safety production and the increase of economic benefits. © Metallurgical and Mining Industry, 2015. Source

HTN (Hierarchical Task Network) planning has shown its effectiveness and potential in emergency decision-making. In realistic emergency conditions, the temporal preferences should be considered. This paper proposes a temporal HTN planner, TPHTN (Temporal Preferences HTN), to handle the temporal constraints with preferences. The planner uses STNP (Simple Temporal Networks with Preferences) to express the temporal preferences information, and extends the operator and method to express the temporal preferences information in planning domain knowledge. In the planning process, TPHTN propagates the STNP top-down, and three definitions of level consistency are proposed to estimate the quality of STNP, and a new heuristic search is designed to choose the suitable operator/method to apply based on the quality of the corresponding STNP. When the planning process is terminated, TPHTN will generate a plan satisfying the decision-makers preferences. Finally, the effectiveness and practicability of TPHTN are demonstrated with emergency logistics problems. © 2016 -IOS Press and the authors. All rights reserved. Source
