Summary
This study introduces a mathematical model to identify and overcome constraints impacting coal mine safety management efficiency. Breaking these bottlenecks during production significantly improves safety outcomes.
Area of Science:
- Mining Engineering
- Industrial Safety
- Operations Management
Background:
- Coal mine safety management efficiency is crucial for preventing accidents, especially in underground operations.
- Identifying and eliminating hidden constraint factors is vital for enhancing safety management.
- Existing methods struggle to effectively address complex constraints in underground coal mining.
Purpose of the Study:
- To develop a mathematical model for identifying constraints affecting coal mining safety management efficiency (CMSME).
- To propose effective measures for overcoming identified constraints, guided by the Theory of Constraints (TOC).
Main Methods:
- Established an index system for CMSME.
- Constructed a mathematical model comparing CMSME ratios with individual factor ratios to identify constraints.
- Employed measures to pinpoint specific bottleneck constraints.
- Utilized internal or external means to break identified constraints.
Main Results:
- A case study at Quandian coal mine validated the model's ability to identify and resolve constraints during production.
- The method successfully improved CMSME by addressing identified bottlenecks.
- The research is currently implemented in select mines with plans for wider adoption.
Conclusions:
- A novel method for investigating and resolving CMSME constraints has been presented.
- Breaking constraints during mining operations positively impacts CMSME.
- Even mines with high CMSME indices can harbor and benefit from addressing bottleneck constraints.

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

01:15Quarrying of Stone

Quarrying is the process of extracting stone from a quarry, where specialized techniques are employed to remove large blocks of stone safely and efficiently. This process can involve controlled explosions or more precision-oriented methods such as cutting and drilling.
One common method involves using a diamond belt saw to cut large blocks from the quarry face. These blocks can be about 50 feet long and 12 feet high. After the initial vertical cut, drilling is performed at the base of the...

471
The compacting factor test is a method used to assess the workability of concrete. It is especially suitable for concrete mixes containing aggregates up to one and a half inches in size. This test involves specialized equipment consisting of two truncated cone-shaped hoppers and a cylinder, all with polished interior surfaces to minimize friction.
The procedure begins by placing concrete into the upper hopper without any compaction. Once filled, the bottom door of this hopper is opened,...

01:26Constraints and Statical Determinacy
899
In structural engineering, the equilibrium of a system is not only determined by its equations of equilibrium but also with the help of constraints. Constraints refer to restrictions on the motion of a system. The proper combinations of constraints can minimize the total number of constraints needed to maintain a system in mechanical equilibrium. When this happens, the system is said to be statically determinate. For such systems, the unknown reaction supports can be estimated using equilibrium...

01:22Design Consideration
475
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.

According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation,...
