Research on the System for Coal Mine Disasters Prevention Based on Modularization Heterogeneous Multi-robot Hong WANG 1,2,a, , Ruiqing JIA 1,b , Hongxiu ZHU 1,c 1 School of Mechanical, Electronic and Information Engineering, China University of Mining and Technology (Beijing), Beijing, China 2 School of Mechanical Engineering, Heilongjiang Institute of Science and Technology, Harbin, Heilongjiang, China a Wanghong_cumtb@foxmail.com, bRuiqingjia@yahoo.com, cZhx@cumtb.edu.cn Keywords: Heterogeneous Multi-robot system, Coal mine safety, Disaster prevention, Emergency network Abstract.
MHMRS applied in coal safety engineering should be subject to the following process: 1) Formulated the task.
The key tasks are to fully survey and map the laneway structure including the position of the equipments, and save the information.
Image materials could be transferred to the ground via network for the purpose of judging any field violation, predicting disaster and taking correct measures by computer graphic recognition method or expert on the ground.
Instant rescue must be composed of diversiform robots according to the task demands, such as: personnel searching robots, communication robots, robots for succor material supplying, ambulance transport robots and robots for leading the personnel.

Phosphate Solubilizing Rhizospherebacterial T21 Isolated from Dongxiang Wild Rice Species Promotes Cultivated Rice Growth Qinggui Zeng1, Fei Luo1, Zhibin Zhang1, Riming Yan1, Du Zhu1,2 1 Key Laboratory of Protection and Utilization of Subtropic Plant Resources of Jiangxi Province, Jiangxi Normal University, Nanchang, China 2 Key Laboratory for Research on Active Ingredients in Natural Medicine of Jiangxi Province Yichun University, Yichun, Jiangxi Province, China Corresponding author: zhudu12@163.com.
Materials and Methods Isolation of P-solubilizing microorganisms bacterial strains isolated from the Dongxiang wild rice samples were screened on modified Pikovskaya’s（PKV）agar medium [19] which contained (L-l): 10 g glucose; 5 g Ca3 (PO4)2; 0.2 g KCl; 0.5 g (NH4)2SO4; 0.2 g NaCl; 0.1 g MgSO4 7H2O; 0.002 g MnSO4·H2O; 0.002 g FeSO4·7H2O and 15 g agar; The pH was adjusted to 7.0 before autoclaving.
Moreover, the development of stress tolerant crop varieties through genetic engineering is a long drawn process, whereas microbial (PGPB) inoculation to alleviate stresses in plants could be available in a shorter time frame.
